I have some questions about my "67 756 gas that I bought last year. It ran a little rough when i bought it, so I tuned it up. It still runs a little rough at idle, but seems to smooth out with more throttle. My mechanic says it is a burnt exhaust valve. I"ve run several cans of Seafoam through it...seems better. How can you tell if a valve is burnt? Is there some simple checks? If it is carbon build up, is there a better way to loosen it?
Also, the TA is out on the low side(I swear it was working when i bought it) and the clutch is adjusted as far as it goes to get the right free play. Do I need to replace the clutch right away? It doesn"t slip and I only use it to push snow and do light acreage work.
