I have an older Sears/Craftsman Snow Blower Moder #536.918301. Have tried to contact Sears about the year of manufacture of this machine, but to no avail.
Can anyone tell me what year machine this is by the use of the model number?

What brand of engine is on the machine?

I'm looking for the same thing. The manual to a Craftsman 24" Snow Thrower536.918301.

The bowout diagrams I was able to get from Sears date it to be from 1980. Here's hoping.
