Governor spring PN 796484 missing for one thing and may very well be your main problem.
I didn't know you guy had those clown riding a toy car type mowers. The first one I seen over here was a Murray and I about laugh myself silly as to size of the guy sitting on it looked it going to disappear. Sorry I can't believe they would make a rider that small. Please forgive me, I couldn't resist.
