Stubby

He has probably got a bit of a black back from his landing .

Make sure its not one of the early ones with one less crank case bolt than the newer ones , but yes , what Matty said !

A properly sharpened chain . A chain that is near the end of its useful working life , if sharpened properly, will have narrower cutters thus removing less wood ( narrower kirfe ) therefore less resistance resulting in slightly faster cutting speed. I some times will give a new chain a stroke or two with a file if I have nothing better to do .

My dog could do a better job using his knob !

This . The smaller the the restriction that you force hydraulic oil through the hotter it becomes . Partially clogged filters have more restriction than clean ones .

Stihl do make synthetic 2T oil but I think that OP was given their mineral based oil . OK for older saws that don't rev so high and generate so much heat .

Mineral based oils are not up to the spec for the piston speed and associated heat me thinks .

This . Its finding one now . I have a 2004 spud ported 346 and it is still going strong .

Stubby here . I don't port my saws . Steve Gum ports them for me . User name spudulike ...Spud to his mates .

Don't try and wriggle out of it now you've been butsed 😀

Knees and elbows 😀

Nice one . Well done . When the warranty has run out , if you want , you can mod it to 372 spec by grinding the internal fins of the transfer covers .

Or even Surrey . 🙂

Luxury . Of course we 'ad it tough ......
