Today I went to take on a large 4 foot diameter stump with my MS 660 I purchased last year.
I started cutting but once my entire bar is in the work, the saw bogs down and the motor won't turn the chain. I back off and run it full idle but once I put a load on it it just bogs down again. It has happened in the past which I blamed on dull chains or hitting something in the stump, but something has to be wrong. I am positive I was using a sharp chain.
I finally gave up and took it to the tailgate. Everything, the bar, chain, nuts, and cover were hot to the touch. I had to put gloves on the handle it. The clutch cover was hot as well. I threw on my 25 inch bar because the saw always seemed under power with the 32 and the same thing happened.
Here is a link to a couple pictures. The first one the dark spot by the muffler was where a little smoke was coming from. The second shows how dirty it was after only a min or two of cutting.

The saw also leaks a decent amount of bar oil when ever I finish using it. More than just a few drops. I looks like it might come from the bottom of the clutch plate.
I recently cleaned the clutch cover as it was getting all gummed up which seemed to give it new life. But after today its like being back to square one.
I am an amateur when it comes to flushing stumps. I bought the saw specifically for this and ever since I had it last year it seems to lack power when cutting big stumps.
Hopefully someone out there can help me.
