Guys, I have a 272 V8 with the Holley teapot carb. The carb has been rebuilt and has been running ok till the other day I came to a stop and it wanted to stall out. Had to put it in neutral at stops till I got home. This was after it had been running awhile(seemed to run better when cold).  When I got home I fooled around with the idle mixture screws and the idle itself and seemed to be idling ok, but when I put it in drive it still stalled out. I'm thinking it's a carb issue but maybe it's not. Any help would be appreciated.
