Scag walk behind with wrong engine?

[Richie F]

Have a Scag SW36-14KA with a Kawasaki one cylinder OHV engine on it.
There is no label on the engine for information.
In the parts breakdown of the mower this unit should have a flathead engine.
Was there a serial number or year that the mower came with an OHV engine?

Most likely you have FC420V series engine which Scag start listing in the IPL when the 7 digit serial numbers appeared. Doesn't list a spec number. Also is could be recoil or electric start version.
