you need to set the choke pulloff for the correct angle so the motor can breather correctly.

It is acting as if the choke is engaged, however the choke is set correctly- it pulls completely open within about 5 min, and the problem is only occurring when the choke butterfly is wide open. Could this problem occur if the accelerator pump diaphragm is ruptured and leaking?

power valve may be the issue if it happens hot.

Duh!! Thank you, Roy! I don't know why I didn't think about that. I used to turn wrenches for Ford back in the early '90's (back in the EEC-IV days) but I haven't had the pleasure of wrenching on an early '70's Ford in years. Just goes to show if you don't use it you lose it. Thank you again- I replaced the power valve and it runs perfectly now. I appreciate your help!
