So, the carb needed a cleaning and a rebuild. I did that, put the carb on and have it purring like a kitten at idle it is running super smooth I did have to back the mixture screw out 2 turns from seated. This is the zenith 228 carb.

When I put it into gear and try to drive the engine dies unless it is getting a lot of gas.

My only guess is a timing or vacuum issue.

Any suggestions or ideas would be appreciated.
