Alright, here's a cold (27F) start video to show how awfully it runs until it's warm. For the first 2-3 minutes, it won't idle unless you keep messing with the throttle. The first crank up, it will only crank with your foot on the floor.

Yea.....and here is after it's warmed up. When it's warm, it cranks perfectly. It will also rev up great. However, if you try and hold it steady at say, 2,000 rpm, it will stay there for a couple seconds, then die off until you play with the throttle again. You can see that in this vid.

At the end of that video, you can see it running about 1,000 rpm. That's with me giving it probably 20% pedal. It just stutters around 1,000 rpm and won't gain any unless you "play" with the pedal. You can also see in that video where it revs to 2,500 or more, then sputters down to idle, then back up....then down, etc. That's with my foot firmly in the same position.

This is a '74 260, bone stock except for a deleted air pump.

Wow, a real aversion to the obvious answer, round tops! Good luck with those flats. BTW, can't seem to get to your movies

Based on your description, sounds like fuel supply. Maybe a blockage? And those carbs, sorry.

If it has black smoke too rich, no smoke too lean.
