Whatever, Sport first or Racing.

I replaced a STK. PZ30 carb, and upgraded to a PWK 28 Nibbi. OK......

When I "GOOSE" the throttle all is good, through to 3/4 throttle good, after that its like it bogs down. wwweeeeeethhhhoooo. got it? I believe I have my air/fuel right as well as the idle, bogs after 3/4 throttle
..Is this an up jet or down jet? Could it be the depth of the needle valve in the main jet? Variables , variables

thanks:
