Few ways to get clearance in a bind.....bend arm down a bit, weld up the hole so there is no nut so the bowl is flush (yes people do it), tilt carb slightly. Or the gayest way, is 2 in 1.

Cant tell by your pics but be sure to tap back the locking tab on the big washer first.
I always leave my clutch plates in place, then back it off.
What SCMF is your gun rated for and how big of tank.
