Re: Flow-Chart for OMC Carburetors??

quote Garry in Tampa:

Frank is right on . . .

Actually, I think both theories are correct. I just didn’t take it far enough. When you bury the throttle at slow RPM, the air velocity through the venturi is low and extra fuel must be admitted via an accelerator pump or otherwise, and once the RPM increases the air velocity increases. Then the holes add air to help emulsifiy and vaporize the fuel and correct the mixture ratio. At least that is how I remember it.
