Dan is this a -26? If it is this is what I do. Set the low end the inside needle at one and one quarter turns out, the high end out side needle at one and one half turn out. now if the eng. spits and sputters from low to high throttle turn the low end in 1/8 turn if the eng just quits as you throttle up that meens it is to lean. now for the high end. if the eng quits at high rpm,like bogs down the high end is to lean. if it four stokes then turn the needle in untill it does start to bog downthen open
it back up 1/8 turn I hope this makes som e sense to you
