Throttle flat spot Tri-Z 250.

[simonswanson]

Have got a clean 85 Tri_z 250.. It runs great at idle and starts first kick every time.. But seems to have a flat spot around mid throttle.. Im wondering if this might have something to do with the vacuum fuel pump ?? Or is it just a carb and jet problem
Any help would be great...

Raise you needle up one. Do that by lowering the clip one position. Your needle handles your mid range. If you need to, do it again but I suggest only one position at a time.
