Steve,
Yes there is a vacuum advance. As you are looking at the carb, the
vacuum tube is sticking out of the throat body. A small tube runs from
there to the diaphragm housing on the distributer. I am looking in my
spares for a spare distributer but can not find one that is good, I may
not have one. I do have a spare Weber round throat which you could
borrow.
