If the pics are any indicator, it looks like its working very well now! Its getting mixed signals from you right now, one minute your fixing it up, the next minute you hitting it in the face. I'd be careful, thats one Beast I wouldn't want to make mad!
That looks amazing Martin! Like others have said, I'm running out of things to say about this amazing machine, but I know for a fact that the Pond's never had a leave their assembly line looking that good! A job well done.
Glad you got it running Martin!! Does that carburetor have a main jet adjustment needle? I don't have any experience with that model of Onan, but I've had plenty of engines that surged until air fuel mixture was set right.
