78 f150 won’t fire

Asked by Mar 24, 2018 at 10:16 PM about the 1978 Ford F-150

Question type: Maintenance & Repair

Hey I have a 78 f150 with a 351m and I’m
stumped as to why it won’t start because it
has a new carb, alternator, battery, fuel
filter and 1/4 tank of premium gas (non
ethanol). Also the carb was sent already
set (fuel and air mixture) and the timing is
set up tdc. So please help me figure this
out
