IMPELLER REMOVAL
1. Wait for engine to cool and disconnect spark plug.
2. Remove housing front cover, by removing (10) screws, around outside of front cover and the exhaust knob
(22) and nut(14).
3. Remove impeller bolt (item #29), lock washer (item #7) and washer (item #28).
4. DO NOT pry on impeller. Pull on center hub area only of impeller. If impeller slides off freely, proceed to
(step 6).
5. If the impeller does not loosen, obtain a 3/4-16x3” (Billy Goat part #440192) or longer bolt. Thread bolt by
hand into nut until bolt rests against the shaft. Tighten the bolt slowly, which will pull the impeller away from
the shaft, remove impeller from shaft.
Using a penetrating oil can help loosen a stuck impeller.
6. Reinstall new impeller in reverse order of removal.

specifications).

STORAGE
Never store engine indoors or in enclosed poorly ventilated areas with fuel in tank, where fuel fumes may reach
an open flame, spark or pilot light, as on a furnace, water heater, clothes dryer or other gas appliance.
If engine is to be unused for 30 days or more, prepare as follows:
Remove all gasoline from carburetor and fuel tank to prevent gum deposits from forming on these parts and
causing possible malfunction of engine. Drain fuel outdoors, into an approved container, away from open flame. Be
sure engine is cool. Do not smoke. Run engine until fuel tank is empty and engine runs out of gasoline.
Fuel stabilizer (such as Sta-Bil
TM
) is an acceptable alternative for minimizing the formation of gum
deposits during storage. Add stabilizer to gasoline in storage container or fuel tank. Follow
stabilizer manufacturer’s instructions to determine proper mix ratio. Run engine at least 10
minutes after adding stabilizer to allow it to reach carburetor.
