Check the plugs on the bottom of the carb body with the base plate off to make sure the plugs are not seeping. That will richen up the idle and low end if they are leaking. put some JB weld on them just to make sure. Also check the float level and fuel pressure. 6.5 lbs should be more than sufficient. I also put a 90 degree spark plug boot on the vent tube facing forward. Do you have electrical tape around the secondary metering rods to control slosh that can splash up around the secondary rods? My cab has a small plate that fills the area around the secondary metering rods but you have to mill the bottom of the carb top for the plate to move freely. What rod size are you running in your carb?
