I go a blown up Briggs and Stratton 140cc lawn mower. For $10 so I could use the mower deck.
I pulled the head. Seems nice.

Here is the head I pulled off a 160cc mower I'm bringing back to life.

I'm not sure what the idea behind this head is. Reverse engineer an ohv to be more like a flathead?

Anyways I'm putting the clearly better 140cc head on the 160cc engine and advancing the ignition timing.
