Thanks for the reply.
I just clamped the shaker down to try again this morning, I fully recharged my air tank, cranked it up and nothing. I started to get angry and decided to grab those can clamps and see how this thing moves. After an initial VERY hard jerk it broke free so I continued to work it in for about 20 or so strokes, turned the air back on and the thing fired up. Must have been siezed up or something. I'll bolt it down and throw a can on and see how it works.
