HI folks - a friends rebuilt A10 ( 57 I think) tightened up and the other day, locked the rear wheel, pulling the clutch in he got it pulled into the road side he then was able to kick it over.
Prior to this he has been having trouble with what sounds like a single tappet noise, this occurs at a specific rev range above and below this it is quite quiet
Other things we thought it could be were a broken ring, small end, lose valve guide.
Is it possible after a partial seizure for the engine to free in such a short time
He does think that the engine has been running hot and has lifted the needle a notch, it also blew a head gasket a month or so back
Any suggestions , I'll pass them on
All the best - Bill
