These Holleys have a primary bowl (rear) and secondary bowl (front) on each carb. I've adjusted the primary bowls on each carb to make sure its not starving during a stop. I've never touched the secondary bowls on either and wondering if i need to set the bowl level on those also?
Any help appreciated, i'm a novice and looking for help. TIA

If your rear bowls are in fact for your primaries then you have your carburetors on backwards. To do this you would need some creative throttle linkage. However, if in fact your primaries are your back two barrels, you might want to turn your carbs around to face the correct direction before beginning any modifications and test them in the positions they were intended to be run.
