<p>Hi John,</p>

<p> </p>

<p>The MS261 does have clutch needl bearing issues, the best you can do is to fit a steel cage needle bearing if you can get hold of one. The OEM part is fiberglass cage and tends to wear badly to the point the oiler arb breaks and excesive wear of the bearing causes the chain brake to fail. </p>

<p> </p>

<p>If the crank is that worn then repair is probably uneconomical but if a new bearing and sprocket will do it, repair wont be too escassive.</p>

<p> </p>

<p>The worrying part of your description is the worn crank shaft - Inspection of the saw, just drop it down and we can go from there - I know Martin well!</p>
