Ok that’s the answer I was looking for. Not the one I wanted but it gives me something to go on. I understand what tubs was saying with the re ring theory. Never anywhere in any manual for any motor do they recommend installing new rings without checking the bore to see if it’s in spec or if it’s egged so bad that you need to bore it and install oversize pistons. I KNOW this is the correct procedure …..BUT we are talking about a 70 year old engine and parts are scarce to nonexistent for internals so for the sake of getting an old low compression engine up and running for a while longer, would it be acceptable to hone the cylinder (can this be done without removing the pistons?) install new rings and see what happens? Or do you just say ok compression is too low so I have a 70 year old conversation piece? yall have been doing this a lot longer than me so I’m open to suggestions. I’ve been tinkering with painting and cleaning it while I’m debating what it will take to make it run, so it’s gonna look like it rolled off the showroom floor regardless.
It's a jungle out there.
