Drilling Holes In Carb Throttle Plate Blades

Guys thank you for all this information. It’s going to take some time to carefully read and understand all this and comment and reply.

I did have the T slots set correctly with the idle screw AND I used the secondary to provide some additional idle speed. But using the secondary is very sensitive. I also installed a wbO2 sensor.

Unless I missed something, I didn’t see any direct reply to my question regarding if tuning the carb by drilling the butterfly’s could improve the idle disparity from in gear and out of gear. Can you guys comment on this please?
