800 qjet, so no jet in the secondaries. I figure it's the bowl running dry because the stock mechanical pump can't fill it as fast as its being used. I've got an oversized needle and seat so if the pump is up to the task it should be good to go. I now have an elect pump installed by the tank set to kick in when the secondaries begin to open. I have not been able to try the system out yet to see if it is the fix I've been looking for. If the problem is still there then I'm going to swap in a Holley carb and see what that does for it.
