I'm trying to get my idle right and turned the fuel jet (B) counter clockwise a little and that got it where it would idle good low. Adjusting C doesn't do much if anything. I've tried to fix the idle with the instructions at the below link but bot much luck. According to the instructions I had the low speed adjustment screw as C and the idle adjustment screw as A.
Anyone know where some good instructions as for this?
I know I'm resurrecting an old thread, but I have the same question. Adjust "C" has no effect unless I back "B" off about a quarter turn. I took the "B" jet out and tried to clean it up a bit, but it had no effect on the running. I have looked everywhere and I'm wondering if the fuel jet is supposed to have a rubber washer/o-ring on it that would prevent it from seating too far.
