Been trying to set the idle on my buggy for the last 3 days and cant get it right. I think im doing something wrong but cant figure it out. Set the metering needle at .7 mm and the mixture screw is kicking my ass. Ill set it to were the wheels just barely turn on my starter box and rev it a few to clear it then apply the brakes. after about 2 secounds of brakes the motor will stall. If i apply brakes then let off the revs sky rocket and wont come back.

BTW it is a OS 21 VG running a #8 glow plug and 20%
I plan on racing this sunday and am wondering if there would be someone willing to meet me sunday morning up at the track to help me out. I'm at a loss here.
Also I anyone want to pit for me?
