Wanted to give you all an udate on my 460's condition. Finally figured out what the issue was with my stalling tractor and it was indeed the carburator. As it turns out somewhere in this tractors past someone decided to modifiy and improve the carburator design. They removed the smaller inner section of the venturi. I didn't see or notice it because they apparently went to great lengths to file and polish the inside wall of the venturi passage way smooth, leaving no trace of the removed center section.
Sure had me fooled......but now with the new venturi installed it works like a champ....almost.
Another question for all of you experts. The governor isn't working correctly. If I gun the throttle, the motor doesn't stall....it keeps varying the speed up and down, and up and down, for quite a while. I've had the governor off and cleaned it up. There's not much to it. The bearings look pretty good, and there's not a lot of slop in any of the moving internal parts. It appears that everything inside is moving freely and doing what it's supposed to do.
I'm wondering if the external spring could be the culprit? It looks good and doesn't seem to be fatigued, but I've ordered one to replace it just in case.
