Before it had 5 hours of running time on it, the paint looked charred and burnt on the intake manifold under the carburetor. I don't seem to notice this on the Chevy 235. The paint under the carb on my 235 is about the prettiest paint on the whole truck LOL. Anybody know why?

Guess I should check that, huh... | | | | | Joined: Sep 2007 Posts: 141 'Bolter | | 'Bolter Joined: Sep 2007 Posts: 141 | I just recently replaced my manifolds on my 228. I used rustoleum "army green" in a spray can, it has burnt near where the manifolds bolt togethrt also. My heat riser valve is fine.
