Thanks guys, that engine was in bad shape and even amazed us it was saved, Jan i used a couple different means of freeing the piston.
First it sat a day or so with Kroil oil then tranny fluid then brake fluid with a rag burning in it like a candle then finally a piece of oak on it and a three pound hammer.
The oil pump was unavailable so i left it out the engine has a dip rod on the crankshaft cap so it will be a splash system.
Bought no parts for it just soak, heat, tap and clean until everything freed up.
I`ll make a couple new vids today, i want to try the zipper in some better grass and another run of the reel mower with a new belt and some tinkering on it.
