My '78 decel valve is adjustable. I backed off the lock nut, turned the threaded post clockwise (which has flats, about 6/7mm) and I no longer have this problem: car comes down smartly to standard idle.

As my problem was identical to yours, maybe this is the fix if you car is running the same unit?

Good luck,
