For what it’s worth, I have my late mother’s snow blower that’s about that age. It’s sitting in my garag. We aren’t there for the winter, but every couple of years I put in fresh gas and use the pull rope to start it. Starts on the second or third try, and it’s a very light pull. I run it out of gas when I’m done.
I typically test the electric start, but don’t ever recall needing it.
Message: don’t scrap the machine for want of a starter.
