I am trying to replace my blown H60 Tecumseh 6 hp engine with an H70 7 hp engine
 

On a group Bilt horse tiller but the H70 has a 1 inch diameter shafts and
the *H60 has a 3/4 in shafts and the original drive pulley won't fit
anyone ever tried doing this?

Why not simply bore the drive pulley? Its only 1/4" difference or
1/8" on a side. Not enough meat in the pulley hub?

Have you searched local small engine repair shops for a 1" pulley the
same OD? If they don't have one, they can probably order one for you.
Also try places like Tractor Supply, Grainger, McMasters.

Yeah, and his polytech probably has a shaper. Groovy!
