90 jetting for cold temps
#1
With the colder temps, our 90cc is hesitating and loosing power.
The carb has an idle screw and an air screw. I was wondering if turning in the air screw will help performance (my experimenting seems to say no) or is changing the needle jet needed.
Any thought of similar experiences welcome.
