I have three of these saws and you can run them all day without over heating.

You need to remove the starter and examine for debris around the fins of the flywheel and cylinder?

You also need to run them to where at wide open throttle, they four stoke out of the cut.

Also 50:1 gas oil ratios are a emissions compromise and not necessarily good for the engine. 40:1 would be better for the engine. I run 32:1
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".
Be all that you can be . . .
