3 and 9 is optimum.

"its fixed"my pilot was lean i went 1/2turn out on my 55 pilot and boom it launched great but still no heat on plugs but i will lean it down this weekend..

the pilot,the main and the powerjet are added together for total fuel supply, you can have the right mixture but in the wrong place. needles determine this,the cut away at the bottom of the slide as well as pilot,main and powerjet.the powerjet can be to rich and affect top end and your launch and then your leaning it back out at the pilot to make up for it, the key is to start at the pilot and get good throttle responce in neutral without running to hot at idle;( around 108 deg.or less), then get the mains to where you get heat and use the powerjet to cool it back down to where you want it.then you can start reading plugs to dial it in further.that is the way I've gotten the best results.. there's a whole lot of different way's to set up alki carbs,but only a few that work the right way! and jetting the others in to perfection is impossible. just my .02
