Finally got some time this evening to tinker with my faltering engine on the 756 gasser. One of the suggestions was to richen the mix as it sounded to some extent it was running lean.
So this evening I let the tractor get up to temperature and backed out the main fuel adjusting screw out 1/4 turn at a time until the tractor would jump from idle to full throttle with zero hesitation. I then turned it in until I got a bit of stumble and back out again until jumped from idle to full throttle again and left it there. Drove the tractor around for a bit, cycling the throttle and knock on wood, I might have a useable tractor again.
Thanks for all the suggestions!!!!
