Putting the mag gears on.

I tried to install one of the mag gears on the mag that has the impulse coupling on it. I took off the nut and went to put on the gear when the impulse coupling came up and unwound a couple of turns. This thing is spring loaded and there is a correct number of convolutions to keep the exact amount of tension on the impulse coupling. A quick call to my Dad and he had a overhaul book for Slick mags. I will get this from him when he comes up to help me get the cylinders on. Trying to get the gears torqued down while keeping them from spinning is going to be hard. There is a pin that comes with the mag but that is to hold the mag gear from moving after you have it timed and are installing it into the engine. It is not sturdy enough for me to torque it. More to follow.
