B) A lot of people fail to watch this one: you must ensure that you do not go so low as to have the sector gear rub on the cutoff lever. This can cause premature wear of the cutoff lever. This can cause more noise than you may want in your gearbox. If you have to raise the sector gear significantly to clear the cutoff lever then the spur gear and bevel gear must be raised accordingly.
This does not refer to the OP situation. He now has perfectly shimmed gears.

I agree... I didn't get any rubbing on the cutoff lever. Even on a 0,2 (final config on a 0,3 to clear the spur), the sector didnt even touch the lever with the GB closed and screwed tight....
I also had a problem with my fire selector going all screwy on me... I was about to give up and take it to a tech when I realised that the irregularity in my selector plate could be causing it.... I looked up pictures of the stock vfc selector plate and noticed that mine was in fact bent, out of the factory!!! I bent it straight like it was in the pictures and the problem was solved!
My shim job at the moment is great, but I feel it could be even better. At the moment, my gears make the same amount of noise as my buddy's G&g m4 commando running fully stock on straight-cuts.... Maybe I should take it to a tech???
Or hone and re-shim it with a better shim set... I used systemas shim set, which only had 0.2, 0.3 and 0.5.... no 0.1 (which I could do without) and no 0.15 (which i feel is absolutely necessary for helicals).
Insights?
