Several potential causes may lead to a chainsaw bogging down. If your chainsaw is bogging down when you give it throttle, this is often a sign of improper gas-to-oil ratio. Many chainsaw operators first notice a problem with chainsaws bogging down when they’re using the chainsaw under load, and this is usually the result of poor air circulation.
I was milling this last week and all of the sudden the saw would die when at full throttle or die if it would have any type of load put on it at half throttle. Basically it would start and idle just fine, and even sounded good at half throttle but when I would push to mill it would die, and if I tried to go to full throttle it would die. This happened Wednesday morning, then ran fine after lunch for a while, I didn’t mill Thursday, when I went to mill Friday morning the saw ran just fine for a while, until late afternoon, but then it started dieing again so I stopped, started the saw Saturday morning just to see if it would work and it worked fine at full throttle.

After one time of puking oil all over a shelf in my garage, I didn’t need the saw for a week or so,,, in to the shop it went under warranty. I have since moved the saw to a home on the concrete floor in the garage where the temp doesn’t swing as much and I almost never find oil under the saw, and certainly not a whole tank getting pushed out like I did previously. As to the cutting out under load, I had this with a weed wacker last year and it turned out being a fuel line that was apparently warming up and sucking some air in at a nipple.
