6.18 Spark Arrester Service
Your
CCP196
engine is factory-equipped with spark
arrester. The spark arrester must be serviced every 100
hours to keep it functioning as designed.
If the engine has been running, the muffler will be very hot.
Allow the muffler to cool before servicing the spark arrester.
1. Remove the three 4mm screws from the exhaust
deflector, and remove the deflector.
2. Remove the four 5 mm screws from the muffler protector
and remove the muffler protector.
3. Remove the 4 mm screw from the spark arrester, and
remove the spark arrester from the muffler.
4. Use a brush to remove carbon deposits from the spark arrester screen. Be
careful to avoid damaging the screen. The spark arrester must be free of
breaks and holes. Replace the spark arrester if it is damaged
5. Install the spark arrester, muffler protector, and exhaust deflector in the
reverse order of disassembly.
6.19 Fuel
Gasoline will oxidize and deteriorate in storage. Old gasoline will cause hard starting, and it leaves gum
deposits that clog the fuel system. If the gasoline in your engine deteriorates during storage, you may need
to have the carburetor and other fuel system components serviced or replaced. The length of time that
gasoline can be left in your fuel tank and carburetor without causing functional problems will vary with
such factors as gasoline blend, your storage temperatures, and whether the fuel tank is partially or
completely filled. The air in a partially filled fuel tank promotes fuel deterioration. Very warm
storage/temperatures accelerate fuel deterioration. Fuel deterioration problems may occur within a few
months, or even less if the gasoline was not fresh when you filled the fuel tank. The Distributor's Limited
Warranty does not cover fuel system damage or engine performance problems resulting from neglected
storage preparation. You can extend fuel storage life by adding a fuel stabilizer that is formulated for that
purpose, or you can avoid fuel deterioration problems by draining the fuel tank and carburetor.
6.20 Draining the Fuel Tank and Carburetor
Place an approved gasoline container below the
carburetor, and use a funnel to avoid spilling fuel.
Remove the carburetor drain bolt and sediment cup, and
then move the fuel valve lever to the ON position.
After all the fuel has been drained into the container
reinstall the drain bolt and sediment cup. Tighten them
securely.
