Stihl MS150T chain brake problems

Having put it together, the clutch drum still spins freely on the crank  and most importantly the bad brake stays in place when applied but with the chain running and stationary.  A longer term solution would be a new clutch carrier without the groove!  Hope this is of some interest.

That MS-150 of yours spend a bit if time idling with the brake on ?

The clutch drum will always have a fair bit of float on it, you have to hold it against the clutch and move the whole assembly in and out showing if you have loose engine mounts. Other than this, check the mounting bolts themselves.

Have you checked them yet?

Probably guilty as charged! Need a re think on working practice....

Yes, checked as per your earlier post and all tight.

Saw was used all day yesterday dismantling small - medium acer, birch and ash trees.

Brake used frequently (and made sure to kill saw sooner, thanks Sawchip).  Band stayed on the drum and didn't jump into the chain once.  As long as the washer lasts, hopefully problem solved.

Will let you know if it returns.
