    i have this problem, but its very rare and only when i've been driving a lot (like 4 hrs straight) i can't seem to pinpoint the problem, but i am still goin thru the routine checks. so, i'll let u knowwhat i find. But, in the meantime, check the dist (making sure its not retarded, causing the engine to eventually foul plugs and shut it down) sry i can't hel;p out more. btw, mine was just rebuilt a while back as well.

    Sounds like maybe not getting enough fuel at idle. Do you have a fuel pressure guage? See what your pressure is at idle. Manual or electric pump?

    i had a 750 edlebrock carb on it before and it was running to rich and did the same thing. so changed to a smaller carb 600 edlebrock it still smells rich.
