Not necessarily... Two strokes require *more* fuel to make power at a lower RPM under load. The main thing is that the 4-stroke goes away when under load.I tune mine on the fat side, I don't mind having to change a plug now and then even though I haven't had to yet. I would like to get into tuning with a digital tach though bc i may be leaving some power on the table.
Probably has cut his hoof off by now...if the Einstein pictured had his druthers and the IQ of a ham he'd probably swap the POS saw for P/U truck wholeness...lolWell, no not really. Technically speaking, it looks like that saw is still alive and well. The truck... not so much.

if you just add more oil it will accually run leaner? I would have thaught richer.Watch out if you change oil ratios as the carb sets the (fuel+oil)/air ratio so if you just add more oil you are actually leaning out the mixture! If you do this then check and retune as necessary.

Not trying to sound like smart @$$. I didnt know that you would have to tune it richer.
Hmm...that is kinda queer looking...perhaps he also has a "wood fetish" or something!Whats he doing to that poor peace of wood?
I've recently started using a infrared thermometer to test the jug temp of gas operated chain saws while into a heavy cut.
Real easy to use and will immediately tell you if the saws jug (piston and cylinder area) is overheating BEFORE it goes into self destruction.
You will really be surprised at how fast (rapidly) a chainsaw engine's jug temperature will overheat when it starts running lean and into a heavy cut, even though the rpms are not being exceeded.
I'm hoping to benefit from the experience of others and learn what the typical causes of saw failure are? I thought of this after reading a thread where somebody mentioned that they scored the piston and destroyed a saw after trying to cut through a difficult stump. It surprised me a little, I just assumed that as long as he was using the right fuel / oil mix that the saw could do it with enough time or worst case he maybe would burn out the chain and not get the job done.
I'm new to saws and just purchased my first good one, this has me a little concerned that I might be doing something stupid and wrecking my saw without realizing it. I do use 91 octane, ethanol free gas and run the saw dry after every use, are there other precautions that people take? Maybe letting the saw rest if its working hard or if its really hot out?
Any pointers would be appreciated.

Hasn't happened to me, yet (knock on wood) but it could still easily happen. You are mixing gas and someone calls or stops by, you grab the wrong can, etc.Straight gassing is not an issue 'you' have to deal with. For the years I've been an AS member not once has an op said 'he' straight gassed a saw. Its always the neighbour, distant uncle, odd guy who gave me this saw etc. So it's always someone else and YOU never have to worry about the issue.
