I recently rebuilt the carb on my '29 Fordor and now it appears to run real rich and sounds like it is missing. I put all the jets back where they belong. The one odd thing was with the rebuild kit from Synders, the gasket that goes between the 2 halves of the carb the side that has the venturi was a little smaller than what the original was. I did not take out the venturi when i cleaned it. Ideas on why it would be doing this? It also appears to surge at times and I can't keep a smooth idle when parked and or driving her.

Thanks everyone!
