New here, spend a while searching for answers and trying this and that with no luck. Heres my problem im hoping somebody can help with. When the engine is cold it will fire right up and run great. Ill shut it off and it wont restart, will back fire thru carb like the timing is off, but if i leave it for the day it will fire up when its stone cold. My base timing is 12* an has 15" of vacuum. Any help would be great, thanks.
