DLTX 53 Update

With some serious help from Gary at Roberts Carburetor I discovered it is a bad exhaust valve. What is a compression number that is considered good? Left cyl was 60 and right with bad valve is 30. I"m trying to determine if I need rings. Thanks for the help

my old 41 A has 100 psi per cyl.

If you are going to take it that far apart to fix an exhaust valve, why not ring it as well? Especially with those compression numbers.
