I have a troy bilt TB4620CC chainsaw that I want to take the clutch off to fix the oiler. The clutch seems to be held down with a nut and there is nothing to hold on to for leverage to loosen the nut because the outer clutch wheel is always turning. Is there a special tool to remove that nut? Thanks for your help in advance.
Dominic.

the clutch nut unscrews the same direction as it travels.
remove spark plug, turm engine until its about half way down the cylinder, use a length of nylon rope, about the same size and quality as the starter rope and feed into the cylinder, making sure you have enough sticking out to remove. turn motor to compress rope, this will allow you to undo nut without damaging piston. when refitting, tighten by hand, assemble and start motor with chain brake engaged to tension
