New guy here. Pics caught my eye because I'm pretty sure its what I have too. My Dad bought it new I think from Sears. The engine and clutch look a little different than that MTD though. Mine is a 3.5 Tecumseh. The exhaust port is out the back next to the intake port like a B&S. The two little L brackets on the fender were there to support the exhaust pipe that extended under the seat. There is suppose to be a gas tank in front of the seat. Mine was also originally metalic green too. The variable pitch pulley on mine looks different though. Either mine is a different model, or the engine and pulley have been changed or different year.
Incidently, I need another clutch if I can find one that looks like the original. My Dad passed away before we could finish restoring and I'd like to keep it as orginal looking as possible.
