Hey guys i've got a 74 fj55 and the thing starts,idles fine but now all of a sudden it sputters and misses under a load. I have put on a new weber, pertonix ignition, fuel filter, i rebuilt the fuel pump. The plugs look fine and were just replaced maybe 1000 miles ago, the wires,cap,rotor have less than 5000 miles and i also put a new coil on it maybe 2000 miles ago. I have a T in the fuel line before the weber for all the excess fuel pressure to return to the tank because it had way to much pressure before and the gas was running out of the carb. the pig has run fine since all of the changes until about three weeks ago then this started out of the blue. Any ideas would be greatly appreciated Thanks Kenny
