Does anyone know where I can find a manual for my old Yardman (MTD) Snowbird? It's right around 1980, I think. It has a Tecumseh SBH 351a, 8 HP as far as I can tell. I'm having a hard time finding info on either the blower or the engine. The good deal I got on it is turning out to be kind of pricey... Oh well, labor of love I guess. Looking forward to getting it back together and seeing how well it does. Thanks very much for all the great advice I got in my other thread about the impeller pulley.
