We took the head off this old T and found the valves just packed with carbon, creating serious compression problems. (I think I know how the carbon got there, so no need to theorize with that aspect of this.)
I'm no experienced hand here, so could use some wet-nursing. Are there any good photos of valves and valve seats showing how bad they can be and still lap in without going to the machine shop?
I guess I could clean everything up and replace the valves, springs, etc., with lapping compound and just see if they will lap in OK.
I'd rather not do that, though, if I had some way to evaluate my problem child ahead of time so I could if necessary just buy a new set of valves, or new exhaust valves if I could get away with that, but then.....
.....I don't know how to make them fit the old seats without a trip to the machine shop.
I may be stuck with the machine shop, but would like you guys to show me a way out. I'm sure you've NEVER confronted this attitude, have you?
