for one valve seat, valve job, two over sized pistons,gaskets. About $600

420 parts

150 machining

But I did spend $70 on over night shipping.

Sounds like it's making some HP. Looks real good too. Can you tell I'm drooling over here?

So Nylyon sent me the electrical documents for the onan. I had the condensor hooked up to the neg side instead of the positve side. So I changed the wire and maybe the problem is gone. Starts every time in the garage.

Oh and I listened to the video sound on the start up. It doesn't sound that tinny.

Just an update on the electrical gremlins. Replaced the condensor didn't solve the problem. Only one thing left after that and that was the $89 trigger. So replaced it about 2 weeks ago. Ran it cleaning about 3 inches of snow. No problems. The spark is noticably stronger. With everything single piece of the ignition system replaced I think its finally fixed. The other reason I know its fixed is there hasn't been any real snow in weeks and its getting warmer out. Thanks for all the help guys.

Any way you can post the electrical diagram for the Onan 20 here too? :thumbs:

So True. I just got a 2-stage blower myself and now all we get is rain......

Glad you got your machine sorted out.

Just curious how did you fix the valve seat that was loose ? Did you have an lager one pressed in or just pean the old one? Or some other method?
