I have a small 16" and the chain has come off too many times. I've really messed up the chain this time I think and will be buying a new one. I've only used it about three or four times. I must be doing something wrong.
I had terrible trouble with a saw that was a 'nut adjuster'. I now have one that has a hand tightener on it. It's a Stihl and for the extra money it's worth its weight in gold. I only use Stihl chains too - much better made and last longer.
I have 2 Poulan saws also - they still work, but using the Ethanol fuel has warped the fuel caps so they are B****** to get on/off. If anyone wants to buy one cheap and can fix the cap let me know!
