Champion 16 dies after an hour of welding

[phaux]

I picked up Champion 16 for pretty cheap in the hopes of rehabbing and selling. After running for an hour it will just abruptly die. After it dies it can be a bit difficult to get to restart and will usually die within a minute or so. Any ideas?

Also, the auto idle seems to just turn the machine off.

Fuel filter would be the logical place to start.

I know on gas air compressors there is a switch that kicks the idle up or down depending on the psi, there is probably something similar on the governor of the welder. Just a thought.

What all have you checked for so far??? Like the previous post, filter, fuel pump, make sure all connections for the fuel line are tight and not pulling in air losing the fuel prime.

I will try changing the fuel filter tomorrow. It's the clear type and looks clean, but you never know.

I don't believe there is any sort of fuel pump as the fuel line runs directly into the fuel tank and I see know electric lines running in after it.

I've changed the plugs, disassembled and cleaned the vacuum actuated fuel valve and will be doing a compression test tomorrow.

There is small solenoid linked to the carb that's supposed to regulate the carb. Just wondering if anyone knew of a way to run some sort of test on it.

The funny thing is that I downloaded the manual and my welder doesn't look like the one in the manual. I also have an extra push button on the the front that says to hold in while starting. It doesn't seem to do anything.

check for an adjustment screw on the idler, there should be one somewhere.

My unit (champ-16) has a vacuum operated fuel pump be sure all the clamps are on the fuel lines and they are tight, if not it will suck air and run lean or out of fuel.

oil may be low, seems to be common....

Pull it and don't push it past the o-ring to check oil level, if its a screw type don't screw it back on to check the oil level just set it on top of the threads.

Sounds like a bad ingnition coil, How many cyclinders does the engine have?
& also what brand of engine? Dave F.
