Hello, welcome to the Skymaster world!
To review, the left mag as looking from the accessory side (rear of the engine).?
IF the 336 is laid out like the 337, I found that a 1/2" racketing box end will JUST fit. To start the nut, if removed, I found a 1/4" flex drive bend 90 degrees with a 12" 1/4" solid extension works best! Also I tape the nut in the socket so it doesn't fallout. On the right mag I found that a 1/2" box end wrench that I heated and bend into a crescent shape works well. FYI you'll only turn the nut about 1/6th at a time. Hope this helps!
