69 Charger 440. Finally got the beast running, but I don't like the "motor boat" sound coming from the exhaust https://app.photobucket.com/u/stump...941f16/p/fdc4576c-e08d-4004-b8e4-7f9c90e01cf1. The entire exhaust is "new" as in never exposed to the elements and always garaged since installed new. The heat riser is just loosey goosey, but I have it tied off counter clockwise to always be open. I just starting using Rec 90 ethanol free gas. Still tuning the carb since I rebuilt it so haven't road tested yet. What do you think?
OK changed out the plugs. Forgot what a PITA they are. Idle circuit plugged? I just rebuilt the card, so where should I be looking exactly?
Edelbrock 750 , your 2 air ,idle needles at the front take them out and spray some carb cleaner down each hole. Screw them back in easy till the bottom out. Then back out 2 turns. That should give you a good start point. Like posted set timing 10 degree advance to start with. Dbl. Ck plugs for fouling, plug wire condition and fire order like posted. Bad distributor cap / rotor possible. I've found cracked ( new ) plugs in the box before. Just be methodical and test fire thr car after each change you make.
OK Cleaned the air/fuel mixture screw holes and adjusted as stated. Ckd timing and it was already at 10. Plugs and wires are new. Cap and rotor fine. I even adjusted the air gap between the reluctor and the pu. It was more than 008. Starts right up. Idles ok but when I gas it from the carb, I get a back fire. Coil?? I've mentioned several times that I now use Rec 90 ethanol free gas for the first time ever. Could this be my friggin problem? It's very frustrating because this car ran awesome before it sat for 5 years. Although garaged and never exposed to the elements.
