This was certainly a low mileage saw when it was run over. Probably still under warranty but that does not include running over LOL. The compression feels great. I took a picture of the sprocket so you could see how little wear is on the saw. A great parts saw if you have one with a bad top end. I would like $100 but will also trade or listen to offers. Take a close look at my pictures to see the damage and also how little use it had.
