2 stroke carburetors use direct acting slides. The throttle cable is hooked to the slide itself and pulls it open as the throttle cable is pulled. They don't dampen out throttle pulses as well as the butterfly/slide combo carburetors but on a 2 stroke engine, there are no huge dips in intake velocity like a 4 stroke because a 2 stroke pulls charge in every time the piston goes up, a 4 stroke pulls charge in only every other time the piston descends.
The trade off on 4 stroke carbs is they can't adjust to air demands as quickly but considering they only pull fuel in half as often, they don't need to.
A 300ex carburetor on a blaster could be made to work but unless you have a blaster you don't care about, and a 300ex carburetor just laying around you'd like to give a try, I wouldn't spend a dollar on it trying to see if it can be made to work.

he was referring to ur blaster, 4 stroke carb on your 2 stroke blaster is not going to be worth the time and money
its a 94cbr900rr screcthed 10 over lowered i use to race but money is to tight some times.
sorry got lost there for a min im back on track it was just a question i had i have 4 fourwheelers just sittin around thought i would take a stab at one and see if it could work
I believe the cbr's use downdraft carburetors that sit in the intake manifolds and then turn up into the airbox above the engine. While the carburetor design is less conventional, it means the air and fuel do not have to make a turn in the intake tract to be pointed at the back on the intake valve and can ram in there faster.
