Ao3 may be down, but this will not stop me from providing piping hot Mustadio/Worker 8 content.
Part of my series of 1,000 word rarepair fics and definitely G-rated. Not terribly romantic, but Worker 8 tries.
Mirrored on my website and Dreamwidth.
Mustadio moved smoothly through the tavern--a deliberate and mechanical step that did not allow Ramza time to ask how things went or Alicia time to giggle as she pushed by with cake. The heat coming off his pale face would show crimson; he did not want it to be seen.
He cut a path to the inn's backdoor, back arched back with the confidence of a man who belonged wherever he was walking. It was only when he arrived at the stables that he let his shoulders droop. Rafa's flighty hen fluttered backwards as he approached, black down floating away from her to cling to the great steel orb that lay nestled in the straw.
He was miserable. He was alone. He was 500,000 gil poorer.
He was going to work on the damned robot.
Worker 8, for all the ill auspices of their first meeting, little minded being worked upon. As Mustadio knocked about its shell, there was a soft purr as the blue veins of its circuitry flamed back to life. When it began to rouse itself, metal limbs unfurling like a chick come out of an egg, its demeanor seemed almost friendly.
"I await your command, Master!"
"Your right arm's grinding again," Mustadio said in a flat monotone. "Your command's to hold still until I get my spanners and some oil."
---
The black chocobo had crept back--just enough to betray her curiosity--by the time Mustadio had the machine's arm off. He sat by gently filing the mechanism, a steady scrape of steel against steel as he tried to smooth out new made imperfections.
"Must've been those bandits out by Germinas. Their swordsman knocked you about pretty good."
"Entity: Swordsman knocked me about badly, Master. It was not good."
"It was good for him."
"Given that he met with 1,257 units of sterilizing heat shortly after, I do not assess the action as desirable."
Mustadio, for the first time that day, smiled spontaneously--without any hope somebody might smile back.
---
"The lubrication in the right arm is now decreasing friction 1.23 times more than in the left arm. I fear this will lead to uneven coordination of upper body tasks."
"You can just say you'd like me to do the other."
There was the thrum of something setting itself into new motion. It's eyes flashed for a second. The chocobo--Mustadio thought he recalled now it had been named Primrose--took a step back.
"I'd like you to do the other, Master."
---
It's arms were lubricated to its satisfaction: a 0.16% difference so he'd been told. Mustadio had started to do a circuit test on the mysterious globes on its back, hoping it would actually be of some benefit and that nothing would explode. He thought, as he applied the multimeter to the presumable power nodes, that exploding wouldn't be the lowest point of the day. He and the machine had some rapport there anyway.
"I can't believe it." He clicked his tongue as the reading registered. "Were men prone to reverse wire hackjobs even when the Saint walked the earth?"
"It is not my place to question the designs of any Master, Master."
"I'd question any Master setting me up for a short circuit, but you're free to question me there."
The came a whir of heat from somewhere within its casing, as if some thoughtworks piece was spinning very hard to process the statement.
"Don't question me then. Take my word for it." He patted its side as it began to slow to a gentle hum.
---
"Might I ask why I am being provided with this much attention, Master?"
Its joints were all freshly cleaned and re-oiled. The reverse polarity orb was fixed and would be much safer in doing whatever it did. Its head had been polished, and it glittered in the cast off lantern light from the streets beyond them.
"I hadn't wanted to pay much attention to anyone else the rest of the day." Mustadio bit his inner lip as he tightened a plate screw. "I made a few miscalculations."
"I am VERY GOOD at calculations, Master!"
"I'm not sure you'd have a better read on her, friend." He picked up his emery cloth and began to work on a patch of rust on its chest. "It wasn't the sort of thing you'd be good at measuring."
"What was being measured, Master?"
Mustadio looked around a moment, uncertain as to whether he was comfortable answering even with only the birds to bear audience. He sighed.
"A woman's regard."
--
He noticed, now that they'd been together for a few hours, that it had begun to mimic some human mannerisms instinctively--that it waved its hand and turned its head with a conversational ease.
"--and this 'lipstick' was supposed to measure units of 'affection'?"
"It was supposed to convey units of mine, Eight. It's not something I think you would understand."
"Affection: a quality signifying emotional preference."
Mustadio nodded. He started to put his spanners away, folding them into their leather wrap in order of size.
"This would be conveyed by the exchange of the 'lipstick.'"
Another nod. He felt very foolish now but didn't want to cut it off.
"And lipstick may be defined as..."
"It's--uh--something a one puts on their lips to look... attractive. I really don't think I can explain."
"Can you specify the originating plant for the stick, Master?"
--
Everything was packed up. The robot was as worked over as it could be. It was almost past the hour when anybody at the inn would have cold meat left to feed a lodger.
"I hope you feel in better shape now. See you in the--"
Mustadio had not quite noticed that they had reached their hands out to one another as if to shake them--not until the machine reached past his to touch his face.
He grimaced as it traced a diesel slick circle over his lips.
"Very attractive, Master!"
Mustadio laughed through the taste of grease. Worker 8's eyes fired brighter.

How to Diagnose and Fix Common Engine Issues in Classic Campers
Classic campers bring a sense of nostalgia, adventure, and freedom to the road, but they also come with unique challenges when it comes to engine performance. These vintage vehicles require a keen understanding of their mechanical systems, as their engines are often older and less forgiving than modern counterparts.
Whether you’re dealing with sputtering, stalling, or strange noises, diagnosing and fixing engine issues in a classic camper can seem daunting. However, with the right knowledge and approach, you can keep your camper running smoothly for years to come. This guide will take you through the process of diagnosing and fixing common engine issues in classic campers.
Understanding Common Engine Problems in Classic Campers:
Before diving into repairs, it’s important to understand the most common engine problems that vintage campers encounter. Older engines are more susceptible to wear and tear, but certain issues tend to crop up more frequently due to the nature of classic camper design. Some of the most common issues include:
Poor Fuel Delivery: Due to the age of the fuel system, problems with the fuel pump, fuel lines, or carburetor can lead to poor engine performance.
Ignition System Failures: Spark plugs, ignition coils, and distributors are often the first to fail in vintage engines.
Overheating: Cooling systems in older campers can break down or get clogged, leading to engine overheating.
Battery Issues: Old or weak batteries often cause starting problems, especially in classic campers that haven’t been driven regularly.
Vacuum Leaks: As the engine ages, vacuum lines can crack, causing a loss of power and poor engine performance.
Step 1: Conduct a Visual Inspection
When you notice performance issues, the first step is always a thorough visual inspection. Start by looking for any obvious signs of damage or wear. Check the engine bay for:
Leaking fluids such as oil or coolant, which could indicate seal or gasket issues.
Worn-out belts or hoses that could affect engine performance or cause overheating.
Corroded or loose electrical connections, especially around the battery and ignition system.
Inspecting the fuel system is also critical, particularly if you notice poor fuel delivery. Check for clogged fuel lines, damaged fuel filters, or issues with the carburetor. In vintage campers, the carburetor may need to be cleaned or rebuilt due to old fuel residue.
Step 2: Check the Battery and Electrical System
Classic campers often experience battery-related problems due to their age and infrequent use. If your engine cranks but doesn’t start, a weak battery may be the culprit. Begin by checking the battery’s charge level with a multimeter. If the voltage is low, try charging the battery fully or consider replacing it if it’s past its prime.
Also, inspect the battery terminals for corrosion. Clean them with a wire brush and apply anti-corrosion gel to ensure a secure connection. Additionally, check the alternator to ensure it’s charging the battery properly. If the alternator isn’t functioning, your camper may run on battery power alone and eventually stall.
Step 3: Test the Ignition System
The ignition system in classic campers is often more susceptible to failure due to older components such as points, spark plugs, ignition coils, and distributors. If your camper is having trouble starting or misfires, it’s a good idea to test these components.
Spark Plugs: Remove the spark plugs and inspect them for wear, corrosion, or carbon buildup. If the spark plugs look worn or dirty, replace them. Make sure the gap is set to the manufacturer’s specifications.
Ignition Coil: The ignition coil is responsible for generating the high voltage required to ignite the fuel-air mixture. If the engine is misfiring or not starting, it may be time to test or replace the ignition coil.
Distributor Cap and Rotor: Check the distributor cap for cracks or carbon buildup. A damaged distributor cap can lead to misfires or poor engine performance. Clean or replace the rotor as needed.
A quick way to test the ignition system is to use a timing light to check the timing of the spark. If the timing is off, adjust the timing until it matches the manufacturer’s specifications.
Step 4: Inspect the Fuel System
Fuel delivery problems are common in vintage campers due to outdated carburetors, fuel lines, and fuel pumps. If the engine sputters, stalls, or has trouble accelerating, the fuel system may be the problem.
Fuel Filter: A clogged fuel filter can restrict fuel flow and cause poor engine performance. Replace the fuel filter if it hasn’t been changed in a while.
Carburetor: Over time, carburetors can become clogged with old fuel residue, causing poor fuel delivery. If you’re comfortable with carburetor work, you can disassemble it, clean it thoroughly, and replace any worn components. If the carburetor is beyond repair, you may need to replace it entirely.
Fuel Pump: If the fuel pump isn’t delivering the proper amount of fuel, the engine will struggle to start and run. You can test the fuel pump by removing the fuel line and seeing if fuel flows when the engine is cranked. If no fuel comes out, replace the fuel pump.
Step 5: Check for Overheating Issues
Overheating is another common issue for classic campers, especially when the cooling system becomes clogged or damaged over time. If the engine is running hot or you notice steam coming from under the hood, there may be a problem with the radiator, water pump, or thermostat.
Radiator: Check for any signs of leaks or damage to the radiator. If the radiator is clogged with debris, clean it thoroughly. If it’s leaking, it may need to be repaired or replaced.
Water Pump: The water pump circulates coolant through the engine. If the pump is malfunctioning, the engine can overheat. Look for signs of leaks around the water pump and check the pulley for any wobbling.
Thermostat: A faulty thermostat can prevent the engine from reaching the correct operating temperature. If you suspect the thermostat is stuck, replace it.
Ensure that the coolant levels are topped off, and always use the correct type of coolant for your vintage engine.
Step 6: Test the Engine Compression
Engine compression is crucial for proper combustion. If your classic camper is losing power, it could be due to low compression in one or more cylinders. To test compression, use a compression gauge to check each cylinder. If the compression is low, it could indicate problems with the piston rings, valves, or cylinder head gasket.
If low compression is found, you may need to rebuild or replace the engine components. In some cases, you may be able to perform a valve adjustment to improve compression.
Step 7: Check the Exhaust System
A clogged or damaged exhaust system can lead to poor engine performance, excessive noise, and engine overheating. Inspect the exhaust manifold, pipes, and muffler for signs of damage, rust, or blockages. A blocked exhaust can cause the engine to stall or lose power.
If you find any issues, you may need to replace or repair the exhaust components. Ensure that the exhaust system is sealed properly to avoid dangerous fumes from entering the cabin.
Step 8: Test Drive and Fine-Tune the Engine
After performing the necessary repairs, take the camper for a test drive to ensure everything is functioning as expected. Pay attention to any unusual sounds, vibrations, or issues with acceleration. You may need to fine-tune the carburetor, ignition timing, or other components for optimal performance.
Conclusion:
Diagnosing and fixing common engine issues in classic campers requires patience, knowledge, and attention to detail. By performing a thorough inspection, checking the battery, ignition system, fuel system, cooling system, and exhaust, you can address most engine-related problems and keep your vintage camper running smoothly. Regular maintenance and timely repairs are crucial for preserving the longevity of your camper and ensuring a safe and enjoyable road trip experience.
Whether you’re troubleshooting an overheating engine, diagnosing electrical issues, or cleaning the carburetor, taking the time to address these concerns can save you from costly repairs in the future.

Fix:
Verify that the components match the board design specifications before starting.
Use a fine file or sandpaper to adjust oversized pins, but be cautious not to damage the components.
If footprints are slightly off, bend component leads carefully to fit.
Issue 3: Overheating During Soldering
Excessive heat can damage both the bare board and the components, leading to burnt pads or weakened traces.
Fix:
Use a temperature-controlled soldering iron set to the recommended temperature (typically 300–350°C for most soldering tasks).
Apply heat only long enough to melt the solder. Practice quick, precise soldering techniques.
Consider using a heat sink clip to protect sensitive components.
Issue 4: Unstable Power Supply
A fluctuating or insufficient power supply can cause erratic behavior in your circuit.
Fix:
Double-check your power supply voltage and current ratings to ensure they meet the project requirements.
Test the power rails on your bare board with a multimeter.
Add decoupling capacitors near power pins to stabilize the voltage.
Issue 5: Shorts and Grounding Problems
Short circuits or poor grounding can lead to a completely non-functional setup.
Fix:
Inspect for accidental solder bridges, particularly between closely spaced pins. Remove excess solder with a desoldering braid or pump.
Ensure all ground connections are properly established and connected to a common ground plane.
Use insulating materials to prevent accidental contact between traces or components.
Issue 6: Incorrect Component Orientation
Placing polarized components like diodes, LEDs, or electrolytic capacitors incorrectly can prevent your circuit from functioning.
Fix:
Always verify the polarity before soldering. Refer to the component datasheet or markings on the board.
If a mistake is made, carefully desolder the component, ensuring you don’t damage the pads, and re-install it correctly.
Conclusion
Fixing issues with your bare board setup requires patience, attention to detail, and the right tools. By systematically addressing problems like poor connectivity, overheating, or improper assembly, you can ensure a reliable and functional setup. Remember, each mistake is a learning opportunity, and with practice, troubleshooting your bare board will become second nature.
