Grandson lost the ignition key to my Toro!

Total Repair Time:: More than 2 hours

Mower body was die cast and in good condition. Engine was burning oil.

Removed engine, no specialty tools required. Honed the cylinder, and lapped the valves. Tip on compressing valve spring for reassembly; compress springs with you finger and tie them with 2 zip ties, cut the zip ties after installing the keepers. Repainted the mower deck and engine. It runs and looks like new. My Toro is a 1999 model .

Leaking gaskets

All the gaskets needed to be replaced on the Briggs 6.75 flathead I was rebuilding. I ported and polished the ports and shaved the eyebrow between the valves and the piston. The gasket set was a perfect fit. It is a monster now. It doesn't sound like a lawnmower engine anymore
