Tried to have someone run the car at 1000RPM and let off the throttle while I'm holding the air plate in position. Letting off the throttle and pressing lightly on the plate caused the engine to stall.
So by the logic posted above, the car is running rich.
Loosened the 3mm mixture screw 2 turns at a time (went up to 10 turns total) and tried each time in between. Thought it was getting a bit better, but that may be in my head. By the time I hit ten turns though, it seemed to be the same.
Would the mixture need to be adjusted based on anything I did? I thought this adjusted the quantities of air & fuel, and that shouldn't have changed.
So I think we've proven that the mixture is OK. I didn't adjust the air plate at all and it seems to be opening/closing fine. It doesn't bind at all.
Any other thoughts??
