Chainsaw Repair

Hi Guys,
Just a quick question for you :-)

I have just started cutting wood to get ready for this winter, I was using my trusty MS271 (about 12 year old now) was using it today, outside temperature was 34C (phew!!)
I cut about 3 cubes of 1 meter logs into 50cm pieces, ready for my splitter. Was just on the last one and the chain stopped moving and the motor would not drive it.
Switched off, left it to cool and now the chain just free wheels, even with chain brake on, I am guessing it is the clutch that has packed up !!
BUT after leaving it to cool for 4 hours the chain is now held by the chain brake.  I havent fired it up yet, in case if its a bust clutch I may do some damage!!

Also, is it possible the clutch can get hot and stop working, it was a hot day and used it solid for approx 2.5 hours, and it maybe OK now its cooled ?

I have my MS390 I can use in the meanwhile and my baby McCulloch too, so not in a hurry, but a Dutch friend is coming up to France in 4 weeks to help me fell a load of Chestnuts, so hope to have the 271 back working by then.

As always any tips, First action to take etc. greatly appreciated.
 

Good deal you found out what was going on with it.
