Poorly Engine.....

I thought I would strip down my old lawn mower engine this evening as I have nothing better to do.
Fuel getting through, that's OK.
Is there a spark. yep, that's OK
Is there any compression, errrrr, no
Take the head off.
Piston Broke (story of my life), No that's OK, good bore no marks.
There rest will be stripped tomorrow, I suspect bad valve seats.
So the valves will come out and I will grind them in to the valve seat by hand.

It's quite straight forward really, old fashion side valve engine, so easy to work on, and it's Honda.
