Rattling Husq t540

Get hold of the clutch drum and try to rock it about the axis of the shaft . If you can it will be that chattering . Worn needle roller bearing or worse locally worn shaft ....

Sounds like clutch/clutch drum issues - probably a dry needle bearing - worth also wobbling the end of the crank to check the clutch side crank bearing. If the chain is done up excessivly it can knock it out

You do have to keep the chain really tight on these saws if you don't it usually flings the chain off

As above, not had it with my 540t yet but the 201 used to do it when clutch springs worn, does it let out the odd screech?

Another vote for the drum needle bearing as it only appears to be on idle,

Yes it is only on idle.

Well that's the annoying thing. The chain on my saw tightens and loosens itself when ever it feels like it. Some days not at all. The next day, ten times damn it!

The chain is hardly ever at the correct tension and I have no control over it.

yes I know. When you turn the chain tensioner it doesn't inspire confidence it feels cheap. The only solution I can give is buy an old 200 and send it to spud. My 540 lives in the shed

That is because the "techshite " bar is de laminating . Get the older type bar fitted to 338/335 and that wont happen .
