So installed the dynojet needle last night. I am waiting on the Keihin main jets to arrive from jetsrus. Looking at the factory pro "how to tune a carb" page: http://www.factorypro.com/tech/carbtun.html, I see that the very FIRST step is to find the best main jet. Then SECOND step is to find the right needle height. BUT you have to select a needle height whether you want to or not in order to do the first step. So what needle height should you use to during the first step?

I assume you want the tip of the needle to be as far away from the main jet as possible?

When I installed the dynojet needle I think I did the opposite (I didn't think about this until today). I put the e-clip at the first notch at the top of the needle (the bluntest end of the needle opposite the main jet side). I also stacked the two washers on top of the needle assembly/diaphram (inside the white plastic spring cup).

Was I supposed to place the eclip as far down the needle (toward the pointy end) as possible? This makes sense to me but I just want to verify with the more carburetor tuning savvy folk here Do I use the washers at all when doing this?
