Thanks Daryl & Grumpy, The number I gave is weird...first part is embossed & the last 3 numbers are Stamped in. The white pen shows the area where the long crack has appeared. The part number is shown at top of bowl.. I recently bought this engine,& assume it hasn't seen much recent action.It goes well..
I have a couple of other Kohlers...a 181 & 161,I think.This looks like them to a degree.Maybe it's a different brand??
