    I thought id throw up a new thread to make it easy for you to see this. i think i may have the answer to your problems...Throw your timing light in the trash and time it by ear. just cause the motor should be at 8* advance doesnt mean thats where it like to be. How to time by ear:
    1. Tighten dizzy bolt so that you can spin the thing by hand with some force
    2. advance the timing alot
    3. start- retard as nessecary so it will start properly
    4. drive- get on it hard too. pull over when you hear pinging (its a very obvious sound) retard the dizzy a little at a time
    5. once you cna get on it hard and hear np pinging youve reached the threshold. drive it a lil more. start it and trun it off alot to make sure it doesnt diesel and it starts ok.
    6. Your timing is set! This may take more time than a light will but in my opinion its alot better!
    7. No more headaches!:D

    I just keep advancing til I hear pinging... A buddy of mine had a old van and it was cool, pull the engine cover between driver and passenger, then when we hit a good hill he'd floor it and I would adjust timing. :doah: :haha: :haha:

    The motor has been dumping alot of fuel into the motor and fouling plugs.. black smoking. It will hardrly run when I mess around with the timing much from 12*BTDC.. I've started to think that I probably lucked out and got two bad carboraters. The Edelbrock sat for over a year. I got a rebuild kit. I think I will try to rebuild it.
    thanks,
    James

    I'd consider taking it to someone that knows what they are doing. That has been suggested once already. You could very well nickel and dime yourself into a corner or cause more of a problem.
