I don't use a chain saw very often on my 5 acres. I have had a cheap $150 Poulan chain saw for the past 15 years. The last few times I used it I had trouble with it. After about 15 minutes of cutting it would run poorly and eventually die. It wouldn't restart until it cooled off. Then it would restart and give me another 15 minutes and repeat. I suspect ignition problems. Changed the spark plug but didn't help. I have a dead tree to cut out in my yard and don't feel like messing with this saw again. Not thinking it is worth fixing. I am thinking of getting a better saw. I have Husqvarna and Stihl dealers close to me. Any recommendation of which brand and model? I probably use a saw once or twice a year for and hour or so, just maintaining my property. Part of me says to buy another cheap saw and get another 15 years out of it. At that point I will be to old to be using a chain saw anyway. Blade length in the 18 or 20 inch range is what I am looking for.
