If you don't know me, I am an ask-it basket. This is hardly the first time you'll hear from me. So, how do they work? What determines good atomization? BTW, I was wondering if anyone has a carburetor that works like an airbrush... Instead of compressed air blowing by the needle and nozzle, just use the intake airflow to pull the fuel out? hey, the exhaust pressure would help pump out the fuel too.
