I have inherited what looks like a brand new snowblower but knowing my father, it is probably over 16 years old. There is no manual to be found and since we just had a blizzard, I would like to use it to dig myself out. I have tried to start it but to no avail. I do know that when we had no snow, someone came out, cleaned it up, put fresh gas and oil etc. and it was running. Of course, now that it's cold and I need it, it's not doing anything.
