The pilot circuit has two adjustable parts. The pilot air screw and pilot jet. The air screw can be located either near the back side of the carburetor or near the front of the carburetor. If the screw is located near the back, it regulates how much air enters the circuit. If the screw is turned in, it reduces the amount of air and richens the mixture. If it is turned out, it opens the passage more and allows more air into the circuit which results in a lean mixture. If the screw is located near the front, it regulated fuel. The mixture will be leaner if it is screwed in and richer if screwed out. If the air screw has to be turned more than 2 turns out for best idling, the next smaller size pilot jet will be needed.

ok makes sense now... I guess they were both right, technically. Just depends on where the screw is located. And it's the Pilot screw that would need to be changed... not the main!

Got it! Thanks!

yea mine is at the back so to richen it i would turn it in and to lean it out i back it out. man i was so confused.

so if your having a slight hesitation right when you should be hitting the power band, best bet would to be adjust the air screw or change needle postion

[pinger.j.]

adjust what way though? richer? or leaner?

if your getting hesitation on the low end, I'd go leaner. but just be sure to check your plug.
