I did open the secondaries some. I have been doing this also, put the secondaries adjustment srew in from the top down for easy adjustment. Even brought the float levels up for crisp idle but that didn;t work well at stops. I will try some more tomorrow, after I get the floats correct. we put a snapon scope on it today to get it as good as it is, got it to idle at about 900, but driving it with the floats set high was a challenge, with idle all over the place. Thought about drilling the throttle plates but did not. It also sucks gas like crazy
Thanks
