Racin'...

I had the same problem when I first got mine. Someone here told me to hold the carb slide closed and turn the mixture screw in. When you feel the carb slide move, that's "bottomed" and then you can back it out the number of turns you want from there.

Working from rotary carbs on my RS4 and MT2 it was freaking me out until someone explained that.

Hope it helps...

BE VERY CAREFUL when you hit bottom on that screw...if the tip of the needle gets mushroomed at all, your tuning turns to doo-doo......
