Black gummy sludge in intake ports
First off, thanks for letting me join.
Tinkering with my new-to-me 1930 A, my carb float had a crack in it so I decided to put rebuild kit in it, while I was at it decided to replace intake and exhaust gaskets, suspected a vacuum leak and thought I would start here. When I removed the manifolds the exhaust ports looked great, but the intakes had a lot of black gummy residue, my question is are the valves going to look similar and what do you old timers suggest.
