I just put the onan engine back in my 318, after the oil pan replacement and thorough clean. I went ahead and did my first carb clean too. Just cleaning, no new parts, spray carb cleaner and compressed air. My problem now is the bowl is running empty and the engine stalls.
The fuel pump seems to be working. If I pull the house off the out, it shoots fuel 2 feet up when I crank it over.
I turned the main mix screw all the way in and then out a turn and a half, also tired a single turn out. I fill the bowl with a cup of gas, put it back together again, turn it over and it will run for 30 seconds, then stall. I check the bowl, and it's empty again.
What should I check next? What am I missing? Before the carb clean, I couldn't run the engine without the choke at least half closed. Now for the 30 seconds before it drains the bowl it runs great, but then, STALLLLL.
