Leave the throttle disconnected and start the engine. If there is no change, I would think it is timing related and would loosen the distributor and rotate it to retard the timing. Something isn’t adding up here.

If I understand him, it’s not that the engine won’t slow down, like a linkage issue, when he slows it down it dies. I would think way rich or way lean. The fact that it will idle slower cold than hot makes me think it’s flooding.

OP- can you get a complete carb from someone just to test? If that doesn’t cure it you have serious problem somewhere.

Per my remark #53 on page 6 of this thread. I think it's the simplest thing to do and if it 'works' it would save lot of ghost chasing . No matter how weird it may be.

Did you ever pull number 1 plug. And make sure dizzy was dropped right? Have you ever actually seen this motor run right? If not I’d go all the way back to square 1 and start over. You shouldn’t be on accelerators for idle. Do you know if it’s the stock cam?
