50:1 premix ok in the high heat?

We're well into heat wave number 2 and my chainsaw guy was saying to not run my saw with a oversized bar too much in the heat or it'll dry socket.

Anyone change thier premix for the lawn mowing tools? I run premium gas in everything and stihl synthetic oil. Not planning on running the saw too hard LOL but want to keep my trimmers healthy. Think I ran 40:1 last summer.

What does he mean "dry socket" . Is he a oral surgeon in his spare time?

Making your premix too rich is probably worse than too lean, so long as it still has oil.
The difference between cold and hot weather is far less than the difference between a cold and a hot engine. The hot engine operates at pretty high temperatures, and a few degrees hotter because of hot weather won't make a bit of a difference.
Don't worry so much about this.

Yeah, worry more about the operator than the saw in the heat.

If you were to measure/monitor engine operating temperature, you would find that it goes up or down almost equal to the change in ambient temperature. It's not like there is an exponential change in operating temperature with an increase in ambient.

Don't worry about it.
