| Stuttering (for lack of any other word) on heavy acceleration. My 56 Custom Royal with a 315 single rocker engine and Powerflite has this stutter when I start form a stop and and stand on it. If I take off slowly it is smooth as a cream puff. It also runs smooth at highway speeds. I took Dave (56D500boy) for a ride on Monday to demonstrate what was happening. Dave asked, did you check this, this and this? Answers are all YES. I have a distributor with Pertronix Ignition currently installed. I did take that distributor out and put my back-up points distributor in to compare. Same S@#t. Today I ordered a new set of premium 7mm plug wires from our local auto parts store, Lordco and will try these as I have changed or tested everything else I can think of. Ideas anyone?

| Not a hesitation due to a bad accelerator pump.

Location: Alaska | could it possibly be the trans. slipping in low gear? This reminds me when my daughter was away at college she would call and have me listen to her car and ask "dad what is this noise" |

| No power brakes. Not transmission, a stall test has eliminated any slip.
I should have my new spark plug wires soon. Once I have replaced these I am hoping this remedies the problem. If that does not fix it, I will start the check list all over.
