I slid it over and it stopped about 31 or 32deg. To get where I felt like it should be, I had to take out about 3/32 of the plastic. Somewhere there has to be an engineering drawing for the machinist to use. They had to set it up in some sort of jig to drill it. Just as easy to set it up right as off a little. Maybe they are on piecework. TBM says SV make all kinds of motors for snowmobiles, chainsaws, etc. Must be some crummy running snowmobiles over there.
