What postion do you have the clip in on the needle?Try moving the clip up 1 groove and then retest.You may also need to tweek the pilot air screw.
Rules of thumb are:
idle to 1/8 throttle is pilot controlled (there is a certain amount of bleeding between 1/8 to 1/4 which is shared between the needle and the screw.
1/4 throttle to 3/4 throttle is needle control
3/4 to wot is the main jet |
