Is Stens phasing out parts for Smaller Kohlers?

[pfrederi 17,645]

I was trying to get a piston, rings, and valves for a K181. On the Stens site all I could find were rings, and a gasket set. Went to my supplier today and looked in his 2009 Stens catalog ...lots of parts for the 10hp and up but rings, rods and gaskets were all I could find for the 8hp.

RCPW had the Stens piston and it was on sale (clearing out deleted parts???)

Edit: RCPW just cancelled my order piston is NLA

I know Kohler still has parts but at $120 for a piston/rings vs about 60 for Stens and $39 for a gasket set vs 23 for stens....
