Thanks for the ideas guys. It is vacuum advance HEI distributor.....that reminded me, I just replaced the distributor a while back. When ya only drive it once a week or two...the memory gets bad. Now I am thinking that the advance in the distributor might be "walking" around....the idle adjustments make very little difference. Now and before at 1and 1/2 turns. Think I will watch college football today, then tackle the problem tomorrow.

Thanks again,,,
GOT IT....I took the vacuum line off the distributor and now it idles and rumbles like it should. So a distributor or timing issue. Not fuel. Awesome.

Thanks, I would have tank out, changed carburetor and stuff laying all over the place....thanks
