Riding mowers

I have it tore down now and putting a new head gasket on it. I had a problem with one valve sticking and it's the valve next to the exhaust stack. I thinks it's the #3 exhaust valve. All of the exhaust manifolds have a drain hole for rain when it's not running and when they get old they clog up with rust then the water gets into the valve guide. I'm glad I caught it early enough that it broke free with some liquid wrench and then I pulled it apart and honed the guide a little to clean it up.

I think all of those older gas tractors are dangerous. I've seen some rigging on the fuel lines and some have caught fire from people running a rubber fuel line next to the exhaust pipe. Someone in my BIL's family died when the tank blew up while running the tractor.
