Can't get it started

Is it a Holley or a Carterbrock? Holley can get gummed up in the little check ball under the pump shooter. It looks like a little cone and if its glued in there no pump shot will dislodge it. youll need to take the carb off, invert it and tap it against a table to get it dislodged. If its a carter, there is a check valve that looks like a jet at the base of the pump, unscrew it and clean it. Also the leather pump seal gets dried out doesnt seal up anymore but it usually softens up with fresh fuel. Cant help you on any 2bbl unless its a Holley that looks like 1/2 an 1850, same check valve. you can also run a wire into your shooter to dislodge any crud.
