I think some thing is missing
 

I got a cub cadet 109 Monday

That's interesting where the piston broke. 109 looks good though.

I thank some one rebuilt it with a cheap kit

What makes you think that?

Could have been trying to start it off ether.
Rod could be gone and just hammered it to death.
Bore could be wore and piston was "slapping".

I don't see any evidence of "cheap parts" from the pics.....

that's actually a common failure on the 14 & 16 K's. don't see it very often on a 10 or 12

I've seen it on my dad's 12 HP K.

you don't thank it was cheap parts?

I think the point is how could you know either way. Could just as easily be Kohler parts you're looking at. Their stuff may be overpriced, but at least it's not unbreakable!

:D

no, probably just a badly worn bore and the piston started rocking bad. loose fit they just hammer themselves apart
