I appreciate the offer and the information. I have an automotive paint supply shop 8 miles from me. I should have went there and asked not assumed any sandable primer would work. Lesson learned. I'm going to save the information you posted and set on it while I ponder if I want to do this all over again. This thing, having a later 4 port 100 series engine in it, required some custom modifications and because of them it is an absolute mfer to get the motor in and out of it with the non removable pull start housing. Even both L / H jets and the idle screw have to come out of the carb to get it in / out. Knowing myself, after a couple weeks of looking at it, knowing I failed, I'll tuck my tail and get back at it. Right now......fukk that mfer. Lol.
