My RP saloon also appears to have little compression, but runs well, climbs hill sturdily and idles evenly. There is no evidence of any crankcase pressure and it doesn’t burn any oil. Given that the standard compression ratio is 4.9 to 1 I don’t suppose that the cylinder pressure is very great anyway. If it goes well, I shouldn’t worry too much.
