My 49 SA is smoking a lot on a cold start. It's blue oil smoke, and clears up after it warms up. It's using oil, but you can't see hardly any smoke when it's working & warmed up. I checked the compression today, (engine cold) and see about 80 lbs in each cyl. While cranking, they all spike up to 80, and immediately fall to about 55 before the next compression stroke. Adding oil to the cyl and checking again didn't seem to make any difference. I'm thinking about removing the head & sending it out for an overhaul anyway, but not sure it's ready for a sleeve kit just yet. It was overhauled back in the early 60's & is mainly a mowing tractor now. What should I be seeing with the compression tester? Can't remember is these have valve stem seals or not.
