We drove around yesterday. Seems to have made a big difference, but I think my carb is dumping to much fuel when you mash it to the floor. It sputters and bogs a lot. It does better in first and second,when the load on the engine is not that much. The q-jet was bad and the holly 750 was a little better. The holly is not mine but a friend is gonna let me run it indefinitly. If the holly was mine I could have swapped it for a 600 yesterday. Timing is at 7tdc. We have an accel hei super coil on it. The holly has been sitting a while, runs good other than the bogging.It has 65 jets in he front. Could it be the power valve?
