[QUOTE=JOE SI;13272518]I'm also having a little carb trouble, and it's really starting to get frustrating.
From day 1 the carb was pulling out of the case, I thought it was just because it was new and had to loosen it and push it back in. Today was the 3rd time running it and it pulled out 2 times during qualifiers. My servo is set fine, but since day 1 it was a pain to tune, my guess is the carb doesn't seat all the way and the pinch bolt don't grab correctly.

Don't do 10th scale but did have a .21 quite a few years ago with a similar problem and what it came down to was just bad luck on tolerance stackups - the 2 pinch bolt halves would bottom to each other before clamping the carb , just ground .5mm off the inner end of each - problem solved.
