I should've said I don't have any SMALLER jets.
The kit's a couple years old. Has always ran fine.
Now I put the need 1 slot richer and it seemed to respond better in the mid-high rpm's.
So I changed the 74 to a 75 and the 42 to a 44.
Low end got worse. mid-high was about the same.
This is curious as everyone has leaned way out after doing the lateral piston ports. perhaps porting my cylinder made use of the extra fuel?
