Tom,
Thanks so much, I'm afraid it's going to have to come back out... I have to wonder if the machine shop let a new or junior guy assemble it, and they broke something or didn't get it in place, etc.
I think the gov rod moves in and out too much, more than in my 212/214, which gives me a bad feeling. I can turn it with my fingers, and I hear the "tab" touching, so I doubt it's broken off, but...
It will sit there and idle pretty good, it's not perfectly in time yet, no use doing that now. But if you just touch the throttle, it's off to the races... If I'd let it, it sounds like it's detonate. Obviously I slow it down right away.
I was thinking it had to do with the spring position, but there is no resistance to pull it back down to reality.
I'll keep you all posted on it. I'm going to take it to the machine shop tomorrow, in the tractor, and let them listen to it. Hopefully he will be gentle with me on the repair, as it was their fault, but it's been 11 years.
Thinking back, he's done 2 Packard car engines for me, countless heads off Cat dozers, Ih farm tractors, 6 of these K series, the 123 out of my Farmall Super C, plus loads of press work.
Curious if I should get new rings put in since it has sat all this time. Guess he can be the judge of that.
Outside of the head gasket, I'm thinking everything can be reused?
Randy
