Reply To: ?????? Question Johnson QD-16

Each ring was springy on both sides (intake and exhaust) not a lot of push,but some. Would anybody happen to know the bore size and tolerance for it to be considered within spec? I’m thinking if the cylinder is really close then I can put new rings in and maybe it won’t be like new but have enough compression to run smooth once again for a little occasional use (after carb rebuild, check coils, clean or replace points and condenser and go thru lower unit.

It's a jungle out there.
