I think I have a Robinson Racing pinion .

Perhaps I installed the motor mount cam the wrong way ? But it only seems to slide in one way so I am pretty sure that is not the problem . What is the little set screw for ? Got to be honest , not to sure about how this motor mount works . What is to keep the motor for sliding back and forth after you set the mesh ?

I am running a 8.5 Turn Novak Motor so I though 18 /81 would be a good start for gearing ? Any thoughts or suggestions on that ?
