Most of you agree there are THOUSANDS of some type of "jetting questions" on the Org....
This is usually about as close as your gonna get depending on other issues. If you find the Fuel screw at less than ONE turn out from lightly seated position (go with next size SMALLER slow jet), and if out more than THREE turns, go with next size LARGER main jet. Then start this procedure over until the fuel jet is adjusted correctly, and it falls between 1 and 3 turns out from seated. this adjustment is usually performed in the garage.
i dont mean to ??? you on this but i sure am confused when you say if i am out more than 3 turns on the fuel screw i need to bump up my main jet.. as i understand what you wrote the main jet is for wide open throttle and the fuel screw is for basically closed throttle or so..
145 pilot/slow jet
boyesen qs3 turned 1 turn out
fuel screw 3 1/4 out
k&n box lid filter
it ran great accept it sounded like a machine gun going down hill closed throtttle. the jetting is what sparks sends in there jet kit. the needle is in the middle.
