Kingston Carb Adjustment

Post by MattM » Sat Jul 01, 2023 1:01 pm

I'm trying to set this Kingston Carb, however, it wants to idle at a fast speed. I've cleaned it out and replaced the original needle/seat with the new ball bearing style. It wouldn't adjust right. I recently went back to the original needle/seat and it still idles fast. When I first started, I set spray needle at 1 1/2 turns, car started. I lowered the throttle to idle with spark fully retarded. I then adjusted the spray needle from lean to rich until I felt it was smooth running, but fast. I tried adjusting the throttle adjusting screw on top, still running fast with the lever bottomed out on post. Not sure what I'm doing wrong, any help would greatly be appreciated. I normally run a Simmons Super Power but found a crack in the casting that started to leak. Trying to get Kingston running for 4th parade.
Thanks,
Matt

Look @ the throttle plate. It should be completely closed with no stop screw engaged. It should parallel the flange. In this position the motor would not get fuel to run. The throttle arm/shaft may have a twist in it such that the plate wont close all the way.
