x2 holley has a vid on youtube how to adjust it just right
If it still does it (have a feeling that will fix it) then try one step larger on the primary squirter. Make sure on both nozzles it shoots out the same I had a bum squirter brand new one drizzled one shot. Replaced it with same size all was good.
