Answers :

Sounds like the valve guides are worn. They will wear excessively due to the fact that
the gas currently sold has less lead content than what was sold when these motors
were manufactured. This also affects the rings as well. You could have the heads
rebuilt with new valve guides that are designed for the new fuel. The lead acted as a
lubricant. Also given the age of that engine, I would rebuild the carbeurator as well
if it exhibits black smoke, and replace the choke during rebuild. A sticking choke
will make it hard to start and plenty of black smoke. Hope this helps.
