Learned something Interesting about my kohler "18hp" magnum engine

[Kris W]

I just learned last night that a few yrs ago my grandfather loaned his argo,
(my argo now) to a neighbour, that returned it with a blown engine... So he took it to a guy that does small engine rebuilds etc. He bored out the block and put in over sized pistons & rebuilt it to solve the problem. So apparently it now has a little more hp.. Can someone tell me how to find out exactly how much ? I know it doesnt realy matter, just currious.

my guess would be that it didnt really increase the hp that much if any.. he prob went from a standard ring kit to either mid size or over size depending on the cylinder walls.

Oh, ok thanks. Well that sucks ! LOL i got all excited there for a min..

Well maybe they upped it to the 20 hp version, maybe not? Just thinking they did may be enough.
