talking about the velocity stacks I have had people say I have it mounted the wrong way?? so what is the right way?? I mount mine with the higher part to the back so the prop pushes the air into it and some people say it should be the other way so the tall side is facing the prop and shields the carb form the prop wash.
Get the stack that is strait across the opening with no angle at all...then see what your "experts" say! You can also make a velocity stack that would be turnable to any angle and see for yourself what works best. Capt,n
