Just got this in the mail today

Well I got everythng put in tonight. The only thing I still need to do is lengthen one wire because it is a little too tight for comfort. It seems to run good and has good throttle response but now I want to advanvce it maybe 2 degrees and see if I can get a little better response out of it. Right now it is set at 5 degrees.

The only bad part is now I hear a little gear wind coming from the motor. When I started I heard a loud pop and then it ran no problem. The distributor was all the way in but it still makes me think the dist. gear and cam aren"t meshing all the way. Does that gear have to wear in a little or should I pull the distributor back out and make sure the gear isnt messed up?
