Hi, I've a 750 with high compression head, quick action throttle and a pair of handed 930 concentrics.

Main jet 220. Needle jet 106 which are both correct according to Haynes manual.

The throttle slide however is 3 1/2, but according to manual should be a 3.

 

Will this affect anything does anyone know?

It was getting harder to start so stripped carbs for cleaning.

It seems to be running a bit rich if anything.

Thank you for your help.
