I have a 383 stroker engine, Holly electric fuel pump, filter at gas tank, mid frame and before carb, runs 7#'s pressure, Mallory ignition with an external Mallory coil, new plugs and plug wires. when I put a new carb right out of the box it will start up idle at 900 runs just fine, next day it starts and wont idle if you run idle screw half way down it will pick up on idle this is third Holly 600 carb bought new. I have checked with starter fluid no leaks at base and intake. When it runs it is so rich it will burn your eyes. If you stay with your foot on the gas and hold at a 1000 it runs just wont idle. anybody have any ideas to help with this problem.

If it is running very rich, you probably have a problem with the carb.
