19.9 Onan
 

Hello Everyone! Got a question about my Onan 19.9 in my 982. Starts right up and idles perfect but after about 2 minutes starts to break up and run very rough then shuts off and won't start. After about 10 minutes fires back up and runs fine then the same thing. I took carb apart and cleaned and switched out coil from another 19.9 I have and still the same thing but not sure if that coil is good or not. Any help will be Greatly Appreciated! Bill

Sounds like a Fuel Delivery problem.

Thanks Roland! I will recheck and reclean the fuel system.

If it does it again, remove the fuel cap to ensure that it is venting properly.

Check the fuel pump too.

Ok! Will check cap. I took fuel pump apart and cleaned, was a small amount of dirt in it but nothing major. Thanks for the help! Will let you know what happens after I check cap.

Thanks 1711 Cub! Drilled a hole in cap and Onan runs fine now! Thanks to everyone that offered me advice! Bill
