Yes, you could. But modifying venturi's is a very ticklish and precise job. A friend of mine did just that (on a Bridgeport lathe) modification on his Amal GP 1 1/2 inced venturi carb. That instrument was on his flat tracker Gold Star. It worked great at wide open throttle, wooley down low, but in flat track racing, down low didn't matter. You were always above 5000 RPM. It must have worked. That was one of the fastest Beezers at Gardena Raceway. Did well at the Sacremento Mile as well.
