Customer Question
Oman 6.5 LP with...

Oman 6.5 LP with 1700 hours runs great for 20 minutes then pops and backfires 6 or 7 times and cuts off. Code 33 came up then code 36. It won't start and pops back thru the carb. No other codes present.

Mechanic's Assistant: Do you have fuel in the tank? If so, is the shut-off valve open and the fuel clean?

Yes it has 2 separate lp tanks and it has a water separator in the line. Plenty of fuel at the cutoff solenoid

Mechanic's Assistant: Do you plan on doing the work yourself?

Its propane fuel

Mechanic's Assistant: Anything else we should know to help you best?
