[RICK LAKE]

commercialcobb Where are your grounds and powers for the MSD coming from?
What coil are you running? # and where? Feel the wires(main ones) are they HOT to the touch?? Heavy red and black.
I am hoping you have done a pressure test and volumne test of the fuel system? I also hope that the fuel line from INSIDE the tank pickup is 3/8" to the fuel pump. The venting on the gas tank is working OK. No pressure or vacuum when you open the fuel door?
Can you can another MSD box and coil for a check that you knows runs ok?
At this time I don't think it's a carb problem solo. Which Quad cfm are you running? What pressure reading do you have on the fuel line into the carb?
If all this checks out, get into the guts of the distributor and look at the module in there.
Does the motor run up to 4,000 rpms without any problem? This is without the burnouts. Normal driving?
Your fuel tank my have NO BAFFLES in it and this will cause the problem too with what is happening. You are sucking air in the tank pickup. Fill the fuel tank to full and try you burnout. Good luck Rick L.
