I know its either the carb, or vacuum lines. Im 90% sure its not the carb, as I heard the engine run before I pulled it. I just cant seem to find what I have backwards. I was hopin someone would have an idea, but I understand that it could be any number of things. I like the carb motors myself, problems like these are the only ones you have, it still runs, if somethin goes wrong on efi, it typically wont run, or REALLY crappy.
