You didn't mention if the engine was on a stand or in the car. Another person had almost the same problem with his engine. His turned out to be an incorrect piece of linkage from a parts car had been swapped in and was binding the linkage so the throttle could not fully return to closed position. A weak spring and vibration was also part of it. If your engine is in the car maybe worth a look. If no linkage is connected and carb is adjusted properly and no vacuum leaks then what about the vacuum or centrifugal advance. Are those working and nothing binding or sluggish in the dist.
