Thanks for all of you guys help.
I just want to let everyone know, that i brought my camper to a guy in my hometown of lafayette la. , and he is known as the
"Oanan Man".
I had tore down my carb twice because i let it sit to long and of course ot gummed up with varnish.
I would spray it with carb cleaner and blow air thru the jets.
I dropped it off to him yesterday am and he called me around 2pm and said you can come pick it up , it is ready.
When i got there , i couldnt wait to ask him what he found.
He said the carb was still blocked up some and he takes them off and soaks them in a strong solution for a few hours.
Puts them back together and makes the fine tune adjustments .
That is the reason when i would put on the A/C it would kill my genny.
It would run perfect without a load , but he said when you put a load, that it was starving for fuel.
Hope this helps someone else that is having the same problems.
thanks again for everyones help.
