Tools:
Screw drivers
1. Remove chain and bar.
2. Remove spark plug and insert short length of rope (enough to stop the piston from completing a stroke) leaving enough to grip for removal latter.
3. Place punch on outer portion of clutch assembly but inside the clutch drum and strike with hammer to loosen/unscrew clutch (counter-clockwise).
4. Remove clutch, drum and worm gear assemblies.
5. Install new parts in reverse order they were removed.
6. On Cover use screwdriver to remove screw on worn cover lid, remove and replace.
Notes: Use safety glasses if using compressed air to blow off debris, disposable gloves are recommended, and remove rope from cylinder before replacing spark plug (it was only used to keep the piston from reaching top of stroke so that the clutch assembly could be unscrewed and screwed back on).
