Hi Guys, I’m cleaning the Onan P220 carb on my 520H. It’s a Nikki 146-0479 carb. I was wondering if the main jet needs An o ring and if so which type and size? There was no o ring when I took it apart. Thanks! John

Well, I put the washers on the flywheel side of the engine and that seems to be working better as far as the starter to flywheel, but the engine won't start. I have a new coil, condenser, plug wires, plugs (not sure about the correct gap though), and a new electric fuel pump with filter. The mower ran one time and mowed the yard a month ago but has not started since then. It started one the first crank when I put all that in new. Is it possible the coil has failed? I even put the old plugs back in to see if that was the issue. The were not burnt. What should I check to test possible failures of the coil or fuel? I think the fuel is going to the carb but not sure if this is enough pressure? Not ready to give up yet...

Hi, I have a Toro mower with an Onan P220 engine that won't start after sitting for a year. Last year I had a Toro dealer clean and rebuild the carb because it was surging. It ran fine for a while but the surging happened once or twice, not as much as it used to. It will start and run if I put gas or starter fluid into the carb but once that's removed it stops. I've replaced the fuel filter and narrowed down what I think the problem is to the fuel pump because I don't see any gas coming out of it. There is a clear line from the gas tank to the pump and I tried priming the line with gas. I can feel a slight suction on the intake of the pump when I crank it but I'm not sure its right. The back of the pump has what I think is a vacuum line attached. There isn't much play in it and it disappears behind the blower housing. Where does it connect to the engine? I'm thinking it might have a leak and need to replace it. Any help will be appreciated. Thanks...ed

Ok Gents, I'll be picking up a rough 520H this saturday; I was told it ran only a matter of months ago until it "lost spark". Being my first Onan, I'd like to know what you onan guys think I should look for! Possibly even a checklist to run through once its home. I'm looking for any and everything! I'll be checking the system overall but I'm hoping for a few Onan tips. Let the instructions and tips fly guys!
