Question

I have a 750cfm Dominator on a 440. The carb runs great until the secondaries kick in. If I stomp it to the floor, it hesitates ever so slightly as the secondaries come in. Last year I had a lot of trouble with it having a very bad stall at take off from the line. Raising the jets from 68's to 76's seemed to help a lot, but I am afraid I still have tuning issues. I have 28 and 31 squirters, and have tried both. Does anyone have any suggestions? I have the regular pump cam that comes with the Dominator (yellow). I have heard I might should try the white one? Please give me any advice, I am tired of stalling on the line!

I would try noticably bigger squirters first, try some 35's in the primary and 40's inthe secondaries. This should show you if you are heading in to right direction.

You didn't say how modified your engine is. Definitely increase the squirter size to 30-35. It sounds like your boosters are not getting a good signal thus your engine stumbles from a lean condition. Larger boosters help overcome the lean condition. Our 451 w/1050 needed 45 primary/35 secondary boosters. That let us back down on jet size.
