Re: No power. Timing or jetting?

GR/NDER /

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?
