I dont know much about all this, but I have carbie cars and motorbikes.
I always wanted to fit an adjustable main jet.
The ones you find on the net are limited to specific carb models and are only adjustable by hand beneath the bowl. I was talking to the local stihl agent/mechanic and he showed me a self propelled mower with a main jet adjutment on the handle right by the users hand. He also mentioned many small airplanes commonly use an adjustable mixture knob in the cockpit.
Imagine being able to turn a knob on the dash and go into lean burn. Awesome! You could monitor with an O2 sensor or vacuum gauge I imagine.
Not many Kingswoods left over here!
