Hey Oldschool, glad you got it going, now you can have some fun.

A bad vacuum advance could cause a lean mixture. That will cause a poping condition. Glad you nailed it.

Glad to see a response when a problem is solved. We out here viewing the forum alot of times never know what solved the problem(s).

oldscool the problem is when you replace 2 parts of which either could be the problem you really don't know which one corrected it. Always change one part and run it before changing another part then you know what caused it. G.M.
