Dual quads versus big hammer!!!...
Hi, did not read the entire thread….but had to deal with one of these carbs before. I noticed the arm for the accellerator pump is in a slot of the throttle Lever, no 1:1 movement when you get on the gas. That caused a stumble everytime…..i put a screw into the Slot to take up the space….now direct movement of the acc.pump arm when the throttle Lever is moving…..no more stumble or lean spot. Check it out!
