Thanks Jim. I guess one could rebend the gear to gain some needed height. One more question...on the GP L4 gear, can you give me the dimension front to back of the large 60 gear? I understand the width across is 3-5/8", I am talking about the other "width" of the mounting area, or would you call that the "mounting depth". Hope I'm explaining this correctly.

The LT-25 with 3 inch wheels has a total height to the fuse, plane sitting level, of almost 6 inches.

I think most of the dural gear was designed back before the popularity of 4 strokes. Excuse the many questions, it will sure help when I can see the plans.
