I picked up a non running 3813 a few days ago. The previous owner thought it needed a timing belt which is common for these. He took the engine off, but never got around to fixing it. When I got it home i realized that the timing was perfect. But, I noticed a crack in the magneto that I could see the copper coil through. Now its back together and I'm only getting spark from one plug wire. I suspect the whole magneto needs replaced, but I don't know much about the mower otherwise and don't want to spend a lot on a magneto...anyone got a used one for sale?
