Do I have enough metal here View attachment 1715470593 to drill and tap the primary idle air bleeds?
(Not sure what the thread size is on the replaceable jets, but I could use a brass set screw and make my own).
My advice is don't bother unless you just like to tinker and you need something to keep you busy. If you want a fully adjustable carb just buy a new one. The new ones have a lot of improvements plus they weigh a lot less. If you really like to tinker then ditch the carb and put a Holley Sniper on there. Then you can play around with air fuel ratio adjustments until the cows come home. The Sniper comes with built in data logging so you can verify what happened rather than just guessing.
