First, welcome to the site !!!!! 2nd, you may need to find a spot to hook the cable a little closer to the shaft for more action. Be sure 90% of your slack is out of the cable between the carb and cable bracket.
You're on the right track and understand my problem. The accelerator pedal isnt providing enough action to open the primaries completely. Looks like altering pedal geometry is probably the easiest.
