Also set the air scews to 7/8 turns out (+/- 1/8 turn), not 1 and 1/2 turns.

Those "O" rings are real important, make sure they are good.

And before anyone sets there Carbs Vacuum readings, they might want to look at this thread.

Bench synch is only to get it running. If there are no air leaks the main thing that causes a racing idle and the cam chain to sound like it's about to come off of it's sprockets is vacuum synch. There are plenty of threads about it here. They have to be as close to each other as you can get them to smooth things out. If not....the cylinders are fighting each other.
