Glad to hear is it running nicely. If you want I can walk you through the carb tuning. You will need the tachometer and vacuum gauge. Smoke is normal on an old engine that has been sitting. Rings get stuck and will pass oil for a while until they loosen up. But oil smoke will only be found at the exhaust pipe. Any other smoke on the engine itself will be paint curing or oil leaks. What paint did you use? I like POR-15 engine enamel. It needs to be cured with engine heat. Regular spray paint will smoke for a while. Anything on the exhaust manifolds will absolutely smoke. Valve covers, did you use new gaskets with a schmear of sealer? All gaskets will eventually leak and once disturbed, they will surely leak. I like cork with a schmear of Ultra Black.
