Bad ring, piston and cylinder

Difficulty Level:
A Bit Difficult
Total Repair Time:
1- 2 hours
Tools:
Nutdriver, Screw drivers, Socket set
Removed air filter cover and filter, handle, cylinder cover, spark plug, compression release valve and muffler.
Loosened carb to access rubber fuel mix intake pipe.
Removed cylinder, covered crankcase, removed piston and associated parts in the kit, and the gasket.
Prepped crankcase for new gasket and checked fitment of new piston to cylinder.
Installed the lubed piston, ring and cylinder and all parts described above in reverse order.
To get the new ring to seat properly I put a teaspoon of oil in the cylinder prior to insralling the spark plug. With the plug installed I cranked it over until it fired off and ran it for a couple minutes to get the ring seated.
