I'm not sure where you live, but if you are close to London, try Kensal Rental Service - 309 Springbank Dr - 519-471-9910. Last year I needed a head gasket for a tecumseh mower engine and after being sent all over the city by several other part suppliers, I decided to just stop in and try them. All other suppliers gave me the stink eye when I uttered the word Tecumseh, but the parts guy here didn't even bat an eye and I left with it in hand it in no time... the price was fair too.
Skinny, just go to the hardware store and buy a shovel. I'm sure the friendly, helpful staff there can lead you in the right direction. Well, maybe not the tall, handsome silver haired fella. All he wants to do is talk fishing, or better yet, BE FISHING! Ahahahahahaha! [)]
