John,
Between 1975 and 1980, different year MGBs had the fuel inlet either on the
front or the back of the carburetor so it is not the placement of your fuel
inlet that is causing your problem. Even though the choke is new, it might
not be adjusted to give enough enrichment when the engine is cold. Also,
have you checked the ignition side of things? A weak or ill-timed spark can
cause poor starting, too.
