Echo saws won't stay running when hot

[Erwin]

Both of my 300 and 341 run very well when I first start them and stay well and ready for maybe 1 to 2 hours. After that it will fire normally with a single pull, just won't stay running as before. Once it cools down, it runs as normal again. The idle was adjusted properly at operating temperature. gas tank is NOT empty. I know it's not supposed to be this way since all my old Echo saws are ever ready. Since it's happening on both of them, it makes me think that it might be the way I adjusted them. Anyone have an idea why this is happening, or any similar expierences with Echo saws? Thank a lot for your input. Erwin

I'm not sure ... Mabey low compression? Post in the chainsaw forum and they will hook you up.

What fuel are you running? Sometimes small saws with their compact size and small fuel tanks will boil fuel in the tank/fuel lines at temps where larger saws have no problems. Runnning high octane fuel lends to lower operating temps a little and may also have a lower vaporization rate and can be sufficient in many cases to prevent partial vapor locking and fuel starvation. Running the highspeed jet a tad richer will likewise, often help.
