Cool. Motor was on points for 2 years. When I tested the Hi Rev dizzy, I don't think I had enough vacuum to pull in vacuum adv. And I haven't drove her much maybe 25 miles ( after a thrash for the rear suspension, and adding stripes, for a friend's Memorial, and another 18 miles to go to ( now x) moms for Thanksgiving. Other than that, just some 3 -5 jaunts through the area out here. Do you need a better Spark Plug Pic? And Thank You for helping me. I may be screwed
