Service Spark Plug
Change the spark plug every 100 hours of operation or once
each year, whichever comes first. This will help your engine
to start easier and run better.
1. Clean area around spark plug.
2. Remove and inspect spark plug.
3. Replace spark plug if electrodes are pitted, burned or
porcelain is cracked. Use the recommended
replacement plug. See Specifications.
4. Check electrode gap with wire feeler gauge and set
spark plug gap to 0.030 inch (0.76 mm) if necessary.
5. Install spark plug and tighten firmly.
Spark Arrester Service
Your engine is not factory-equipped with a spark arrester. In
some areas, it is illegal to operate an engine without a spark
arrester. Check local laws and regulations. A spark arrester is
available from your nearest qualified service center.The spark
arrester must be serviced every 50 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 spark arrester.
• Remove spark arrester screen for cleaning and
inspection.
• Replace if screen is damaged.
Air Cooling System
Over time debris may accumulate in cylinder cooling fins and
cannot be observed without partial engine disassembly. For
this reason, we recommend you have an authorized Briggs &
Stratton service center clean the cooling system per
recommended intervals (see Maintenance Schedule in
beginning of Maintenance section). Equally important is to
keep top of engine free from debris. See Clean Debris.
Clean Combustion Chamber
We recommend you have an authorized Briggs & Stratton
service center remove combustion deposits from the
cylinder, cylinder head, top of piston and around valves per
recommended intervals (see Maintenance Schedule in
beginning of Maintenance section).
