Terry thanks.
But i have a HS motor with a taper. i want to have a pulley machine to fit the crank.

i guess i was not clear on my original post.
But i need to know if this is a stranded generator taper of some kind or some off the wall thing.

i know this much it is the same as the 2 stroke pocket bike taper. I needed a clutch and all i could get quick was a 2 stroke clutch and it fit fine.

i know we have some engineers out there, so come on boys dig out the books that you were over charged for in collage and help a poor good ol boy. Thanks Don
