Jones just wonder if I should be albe to ajust the Idle mixer screws at 1200 rpms ? I thought I should ? and if the jetting and air bleeds was close ?




The throttle plate is open to far so it's past the idle circuit. Are there any holes in the throttle plates? If not try opening the secondary plates and closing the primary some. If that doesn't work you may need to drill holes in the primary plates or if it has holes they may need to be larger. This is so you can get the air flow needed but still keep the plates closed enough to use the idle circuit.




This what I thought. But I am not not a great carb guy so I thought maybe I needed to change the IAB or something like that. drilling the holes is a old school trick I have done to older carbs that did't not have adjustable air bleeds.
