14.5 to 17.5 swap?

[resuwrecked]

Hey everyone. I have a '70-something cub cadet with a seized 14.5hp kohler. I found a local listing for a 17.5 kohler. Do the 14.5 and 17.5 have the same mounting pad bolt pattern?

And if i end up rebuilding the seized 14.5, where is the best place to get a complete rebuild kit?

Hi there,
you should have no problems swapping up to 17.5, as long
as both are vertical crank, bolt holes should match. I have
seen one kohler with a metric (25mm) shaft but most would
be 1". Only other consideration might be exhaust direction,
but cutting the hood may be an easy fix.

I hope he can! As I'll probably swap my mower's engine some time. It is only a 2.6HP, and I would like something more powerful, like perhaps a 4HP.

The 2.6 works fine, but whenever it hits a damp/dense patch of grass the engine shudders and slows down in RPM's, and only picks up again when it is past the damp/dense patch.
