Hunting usually means it is running lean. I would check the anti-diesel solenoid to start. Are you getting 120 VAC out of it?

frankiesdoggies

Yes I am if I close the choke half way i can run one ac and water heater

Ok. That is good news. Sounds like you are running lean. The anti-diesel solenoid can get stuck/fail. That will limit fuel flow. The fuel pump does have a filter on the input I believe (5e does), worth checking. Plus check the electric connection at the fuel pump too, mine was bad.

It dus have filter right before pump I removed it.. And it was clean I had the carb bowl off I seen that anti disal valve I should of cleaned it do u know part number so I can get new one??

The anti-diesel solenoid is usually easy to clean, if it has failed wont help. You can order thru www.partsfortechs.com

BD, I think you have become the resident Kohler expert - I'm guessing experience not necessarily gained by choice!

MT: took me 11 years to get mine to finally run. many hours in the hole with that thing.

BD is working on his next profession when he retires!   I'll add that I agree it sounds fuel related and running lean.  If it actually shut down on load, then I'd say possibly one of the coils (which is an issue I've had).  Keep us informed.

I can get one ac to run and water heater but not second ac it won't stall it just bogs down

It funny I'm in this 3 days and I think I can work at kohler I can fix every ones gen but mine is almost there just not 100% yet

frankiesdoggies

Ok I got it the coil pack in rear was bad I pulled front wire off as it was running it stalled I pulled back one it ran the same

Wohooo!  I got one right!  Good to hear you've got it solved!  On my genny that one got the best of me and I had to have a mechanic help (didn't help it was mid summer & I wanted the genny working immediately)
