OK, basically when the saw is idling, the clutch should be spinning around inside the clutch drum with no contact between the clutch shoes and the clutch drum.

 

You usually get a little friction between the crankshaft and the drum and clutch but this is so small it wont effect the idle.

 

If the saw is cutting out when the chain brake is applied, the application of the chain brake is increasing the contact friction between the previously mentioned parts to the point that it is dragging down the revs at idle to the point the saw stalls.

 

It may be the bearing is shagged, twine around the crank shaft end and washers is a common one (probably not in your case as it has been cleaned), a busted clutch spring can do it as can just wear and tear on these parts.

 

The MS261 does have well documented issues in this area:thumbdown:

It wouldn't but it would explain why the drum not going on.

 

The cutting out could be many things. Like carb issue.

 

The impulse line do have a tendency to go on these.

 

Is the carb adjusted to factory, and does it make a difference if adjusted. Also what is the plug colour?

 

Cheers for the info and yes it does seem the ms261 is a a well documented failure

Yes the spark looks fine as do the clutch springs
