Hi there guys - just a newby - I'm helping my son with a '78 that has had low compression on the right cylinder. We tested valve tappet clearances etc, changed plugs. Short of it we took out the engine and pulled it apart - alot of carbon around the valves. Re ground the valves and cleaned the heads. Slight bit of scoring on the cylinder - front cam chain guide disintegrating so guessing it got churned up? - not sure.
Anyway we got new seals etc / rings from Geoff's XS - great guy.
We got a first oversize set of rings with a standard bore.
Question - we filed the rings to give the proper clearance (.2 - .4 mm) and they are fitted. Engine is not running yet. Will they be ok? I am concerned with the slight eccentric nature of the new rings vs the bore or is this so small it doesn't matter?
Thanks! Any suggestions comments welcome
