gas primed
have a 1978 chevy cheynne full size pu two wheel drive and 350 engine. Has dual tanks.
My problem is when the pu sits for more then 24 hrs I cannot start it without priming the
carb. I even have a completely different engine and carb and it still does this. Does
anyone know about a switch fuel switch on the fuel line that would not close or whats
happenning
