Decided I needed another winter project. I dug the 58 out of the back of the shed; I've had it for so many years I forgot what I checked and did to it. It was given to me and I know I never had it running seriously on a boat and I can't remember if it ran well. I started with the compression and I'm getting 80 exact on both cylinders. Is this good enough for me to start on the rest of the motor (carb and ignition)? thanks

id go for it at 80 psi as it should get a bit better with some run time. its good that its even between both cyls.
