Re: Holly carb problem

check the pressure on your fuel pump first

Re: Holly carb problem

take fuel line off carb// place in a container turn engine over// factory spec is about 1 pint pumped at cranking speed in 30-45seconds

Re: Holly carb problem

Wouldn't be the carb...maybe the fuel filter is backwards...or the pump isn't good...
Take the fuel line off the carb and turn it over...^
