Just did 2 to 4 bbl swap car starts wont stay running please help

Very helpful! A hell of alot clearer now to. Now it all makes sense it might be a good idea to invest in a tach and a dial back light so that i can get my car running as good as it possibly can. Thanks so much for all the info man. I swear if it wasnt for the people like you and this site id be lost when it comes to my old mopars.
