Trying to follow the tuning steps in the Holley installation manual for a 4160 600cfm 4 barrel.
The second step is to adjust the idle, the instructions say to move the primary and secondary stops the same amount so that the throttle plates move equally. The primary is obvious. The location of the secondary has be stumped. They show a picture of it in the manual, however, it is a close up of the screw, and there isn't enough of the surrounding body (for me anyway) to id the location. I have searched all over the thing and have identified everything else on the thing, but I can't find where this secondary idle stop screw is hiding.
Can anyone tell me if it is on the left, right, front, back, top or maybe in the bowl?
Thanks,
Don
