I have a Strikemaster 3 Magnum ice auger that I haven't used in around 10 years. I pulled it out and filled it with the proper mixed fuel, took out the spark plug and cleaned, and reinstalled it. It looked good. Anyway my arm gave out after 100 pulls or so and it still won't start. Any suggestions from those of you that use these often. I have long lost the manual and can't find one online to troubleshoot.
