The 351w in the tr7 wants to foul plugs extremely bad. The plugs are black so it is not burning the gas. The motor is basically stock internally it has a 600 vc holley on it. I believe it is not getting enough fire. I plan to swap a blaster 2 coil on it tomoorow. It has duraspark ignition on it. Any more ideas on what it could be
I was going to say check the float levels, but if it was doing it with the other carb, I have to agree it might be too much fuel pressure. What kind of pump does it have? Does it have a regulator? Weak spark might cause it to start hard, but it should still burn whatever gets in the cylinders.
