Tiller 90 degree gear box
 

I just picked up some parts for my 1450. I found a tiller, snowblower, 1650 tractor (minus motor hood and side panel) and what appears to be a new or rebuilt K341, at least when you look in the spark plug hole the piston looks like it was just machined. Anyway my real question is what is the difference between the 90 degree gear box’s for the snow blower vs the tiller? Is the same gear box used for both attachments?

Same box. Different gear ratios.

This isn't related to you question but i thought i would point out that the spark plug is over top of the valves, not the piston. I don't even think you can see the piston looking through the spark plug hole.
