HI guys i have a 1985 plymouth gran fury and i changed plug wires and plugs along with general maintenance tune up. Filters, oil, hoses, everything. It ran great until i decided to change my fuel filter and it started leaking gas from the carburetor. i rebuilt the carb and found out that the floats were stuck so i freed them and now the carb is fine but now it wont fire. I did the old screw driver in the #1 plug wire trick and put it next to some metal and there is no arc or spark. i cant figure out whats wrong and its very frustrating. please help. thank you
