Make sure there is no demand on it when you are starting it, and check the gas. It sounds like a fuel problem more than anything. Make sure it flows freely, no clogs, no clogged filter, squirt some fresh gas in the piston and fire it up, see if the fuel pump , if there is one, is pumping, check the fuel line, Take it off the carb and see if it flows out, pumps out, Blow back through and see if it is clear. How old is the gas? Check it out, hope this helps.

Miller Legend welder. Onan engine starts and runs a few minutes then dies. Why won't it restart for 5 minutes?


Some engines have a low oil cutoff switch. If the oil level drops to a certain point it kills the engine. Your oil level may be close enough that after starting and running for a little bit the level drops enough to kill the motor. After sitting for awhile the level rises enough to allow the engine to run again check the level and add oil if necessary.
Hope this helps.

My onan 4.0 generator will not idle and is back fireing while trying to run it will run fine for ten min then starts trying to die and starts back fireing when I try to keep it running


check for a faulty sump oil switch . check for faulty coil ( magneto on the flywheel) as the time it runs suggests that it is breaking down internally.

The engine has low oil level shutdown. It may be the reason for stopping.

Use the welder only at level condition. Check the oil level, before every start.
If no result, find and check the oil sensor contact (if possible replace with good to check). Try with disconnected and shortened contact prior to buying a new one.

Other possible reasons you already checked

Onan generator dies after 2-3 hours of running , wiil not restart rigt away wait 10 minutes starts no problem then runs for 15 minutes shuts down and keeps reapeating on 15 off 10


This sounds like overheating. These small generators don't have overheating protection, but if a low oil pressure or low oil level is present it may be the reason for stopping.

Check the oil level in the starting conditions and again when it stops. It may become under the "stop" level and after some time the precipitated oil has reached the "start" level. The same may be with oil viscosity and oil pressure.

Try to add some oil or change the oil with bigger viscosity.

Gen starts and runs with rocker start button pushed in..stops....


Cleaning the brushes is used to address an AC output problem. If the generator would run for a few seconds after letting go of the button, then this might apply.

But, since yours is dying as soon as you let go of the button, that tells me that you are probably looking at a low oil condition, or a sensor / sending unit failure for oil level.

Without spec number, hard to remember if the sending unit is for low oil pressure, or low oil level. Either way, the ignition is being grounded. First, double check your oil level, make sure generator is reasonably level. If still not resolved, then locate the sending unit, and remove the wire that is on the end of it. There should be a connector either a few inches from the sending unit, or a few inches from the control board (coming from big white plug). Disconnect at either place. Try starting again. If it starts this time, double check oil levels. If those are fine, then sending unit has failed, or oil pump (if pressure unit) has failed. In either case, don't run for very long until sending unit is replaced, just in case.

Lincoln Welder Generator Oil Question


Better late then never! im-308 total lube oil is 4 pints for a briggs and stratton engine
.
and 3.5 for an onan engine with filter change.

Note: an internal kill switch will shut down the engine if the oil level drops below a minumum

operating level on the onan engine only.

on your welder use a multi-viscosity sae sj grade or better oil. recommended is 10w-30.

if you work in cold environments use 5w-30 oil , it's thinner and will flow easier

during cold starts. Synthetic oil is better. just more expensive. change oil at least

every 100 hours for better performance. good luck!

Onan 4000 start good runs only ten minutsand shuts down,starts up


First locate the oil pressure switch and see if you can bypass it,then see if it runs. If not check the fuel filter and fuel pump,make sure solonoid for fuel pump is kicking on.

ONAN 4000 RUNS FOR ONE HOUR AND DIES--ANY IDEAS WHY?


Try to restart to see what happens. However, make sure to have a volt meter to check output voltage. You may be loosing voltage and therefore it shuts down. Check oil pressure switch, rings, brushes. Replace brushes if they are less than 1/2" short and clean rings with emory cloth until copper is noticable.
