Engine won't run smooth for longer than 5-7 mintues

Kohler 12 hp new on lincoln gen/welder (27 hrs on unit) starts good runs very smooth then 5minutes of running drop down in rpm to almost nothing then will pick and good for another 5 mintues then does the same thing. Does this under load or no load high idle or auto no differance.

    Choke was not on. I was running under load as a gen. (20-25 amp) when this started.

    is your choke still on if not check and see if it welds alright if it does then its a petrol and noise reduction on

Why won't it start?

as with any gasoline engine, you need, fuel, spark & air, take a moment to follow the progression of each of them, you will figure it out: example, test your ignition switch, clean, new fuel, getting spark to the plug? do you have a fuel stop solenoid attached to the carburetor?

I have a champion 10000 watt gen welder won't bur

Make sure the switch for remote power or control at machine is on the right setting. It will arc but very faint if this switch is not on the right setting.

Whats making the fan on my welder not work

The fan motor has probably burnt out, i see this alot...make sure the connections are can try putting 120v to it directly, if it doesnt run you need a new one...if it does then you need to check all your connections

Our lincoln stick welder started throwing breakers, then just quit. the fan won't even come on

Unplug the unit. Remove the back. Take the input wires off the transformer. Using a DMM check for resistance. It should be more than zero around 2 to 5 ohms. Remove the output and do the same thing. If either winding is at zero ohms your transformer is bad and I would suspect it would cost more to replace than a new unit. If you need more help let me know.


Thanks for using FixYa and the generous rating.

Licoln welder is old with 4 cylinder continetal gas motor cant figure out how the ingnition magnito is supose to be wired i thougy just run 12 volt to mag but points keep burning up

Not exactly familiar with this motor but in most ignition systems with points, the wire running to the points is a special resistor wire. It has a certain amount of resistance built into the wire to keep from burning up the points. Maybe you can find some kind of older motor with points and order a resistor wire for that motor to use in your lincoln if you can't get the right wire from Lincoln.

16 hp briggs on 225 welder. older 1 lunger. when it gets heated up it starts missing sometimes back fires then dies. runs perfect until then. replaced or rebuilt most everythingincluding coil. whats the...

Have you checked the compression both cold and hot if not do so... I think what you are going to find is you have very low compression when the engine is warmed up. what is causing this is the intake and exhaust valves grow from engine heat reducing valve clearance which is causing your intake valve to be slight open or no spring pressure allowing compression pressure to open the valve and blow back throughthe intake. Good luck

No welder output

Sounds like a control board problem, would much more info to diagnose.

Welder not charging battery

Most engine driven welders have the charge armature located underneath the flywheel of the engine, but you need to check a couple of other things before you start tearing down the engine. Look for a small rectangular module on the blower housing of the engine, on a Kohler this is at the side, on an Onan it's at the top. This is the rectifier/charger module and it will have 3 wires, the 2 on the outside will be the AC from the armature, and the middle one is the battery charge positive. With the engine not running, use a DC voltmeter to measure the voltage between this middle tab and the engine block, you should see a voltage that's very nearly equal to the battery voltage. If you don't see a voltage there you may have either a blown fuse, a tripped circuit breaker, or a broken wire leading to the battery. On some welders the fuse or circut breaker is inside the welder cabinet on the bulkhead between the engine and the generator parts of the welder.
If you did see battery voltage at the charge terminal, start the engine, switch the voltmeter to measure AC voltage and measaure the voltage from one of the outside terminals to the other, you should see 15 volts or more (be careful not to short out anything). If you get a nice AC voltage, switch back to DC and measure the charge output again (engine block to middle tab), it should be greater than the battery voltage we measured before and it should be slowly getting greater, if not the rectifier/charger module is bad.
If you didn't see enough AC going into the module, stop the engine, disconnect the plug from the module and use an ohm meter to measure the resistance between the 2 outside wires that go back to the engine, something between 100 and 1500 ohms is good. If you measure an open circiut (OL on my meter) or if you measure 0 ohms, the armature is probably bad. You have to take the flywheel off the engine to see the armature. If you got a good restance reading but the voltage is still low you may have one or more broken magnets inside the flywheel, again you have to do some serious disassembly to see if that's the case.
