I inherited my dad's Stihl after be passed away. He died in 1989 so that gives you an idea of how old the saw is. It sat for close to 20 years as I had no use for it. In the last couple years I've started using it again and it runs and works fine once it's running, but it can be incredibly hard to start. It's usually easier if I spray a little starting fluid into the carb, but I know that's not ideal and even so my arm sometimes wears out before the saw starts. I don't have any experience or knowledge of chainsaws specifically but I'm generally pretty handy and know my way around car engines so I'm hoping if someone can give me a starting place I can get the saw running better myself. I don't use it often enough to make it worth putting a lot of money into it. Two things I have done are sprayed out the carb with a carb cleaner and checked the spark plug. Although very old it looks like it's still in good shape. Any ideas on what I can start looking for to correct my hard starting problem? Thanks!
