Always shim any new gun as soon as you have a chance.
They DON'T shim them from factory, they just throw shims in there and CALL it shimmed.
If you have a vernier it'll make shimming MUCH easier and MUCH faster.
Just don't let the gears rub together, don't let the sector gear squeeze the tappet plate against the mechbox shell, and check the bevel-pinion height and make sure the pinion fully engages the bevel.
Someone will tell you the bevel-pinion height is the most critical thing in the world, but it's not. As long as the pinion fully engages the bevel when the motor height is set, there's no need to split hairs. Any fine tuning of that adjustment can just be done with motor height afterwards.
