After shoveling our driveway, I decided that a redundant starting mechanism on the decrepit snowblower was definitely my ticket out of further back pain. (Electric starter repair/replacement might be my next instructable.) I also had to fabricate a handle since I wasn't about to fork over any money for a plastic handle.
As it turns out, the only disassembly was to remove the rewind starter housing from the snowblower (4 bolts).
Step 1: Tools/Materials Required
1. Hot Glue Gun (optional, I just like to glue stuff)
2. Sharp Knife
3. Lighter (please be careful with fire, do not use this near the snowblower or any other source of gasoline)
4. Locking Pliers and Drill Bit (I have yet to aquire a free drill, so I improvised)
Materials needed for Repair:
1. Dowel for replacement handle.
2. Latex Cork
3. The new pull cord. (I found some snowmobile pull cord at my favorite hardware store)
Step 2: Remove old pull cord.
You can discover how the rewind starter operates by turning the pulley both clockwise and counter clockwise. The "dogs" or teeth engage when the pulley is turned counter clockwise.
When attached to the engine they function to grab the interior of the flywheel and turn the engine over, then they retract as the pulley turns clockwise. The "dogs" are angled in a way to minimize the damage caused if they were to fail to retract, or if the cord is pulled again while the engine is operating.
