Oh that's reassuring anyway, yeah slightly worrying. Good job I'd not fiddled with it yet to make it a 372. :-)

A saw so new shouldnt be knocking but engine noise can be:

 

Small end - light tapping

Crank bearings - whine, hollow drumming noise, rumbling

Big end - Thumping knock

Piston slap - on idle - a metalic knocking

Clutch - same as above

 

On crank bearings, you can usually hold the flywheel or clutch and wobble the crank to feel the play.

 

On small end, big end etc just wobble the flywheel to and forth gauging the amount you can move it until the piston moves or strip and inspect the play/parts.

 

You may have a fault but the dealer should help.

Thanks for that spudy, I thought it was bottom end, but since you mentioned piston slap it does resemble the noise subarus used to make! And it is on tick over when it happens.

 

I'll speak to them asap

It isn't a ring ting ting noise is it - could be the clutch tapping the clutch drum on idle.

 

Easiest way of finding out if it is the clutch is to remove the thing and run the saw up:thumbup:

 

Piston slap generally happens on older saws once the piston skirt wears - 026/MS260s are quite bad for this - some saws have cylinder extenders that go down in to the crankcase to support the piston at BTDC where this wear is common.

No it's defiantly a muffled knock not a ting, I know the noise you mean and it's not that. So I am still convinced its an engine knock.
