MUFFLER

Replacement parts for the WARNING muffler must be the same and

installed in the same position as the original parts, other-

wise fire can occur.

If muffler is equipped with spark arrester screen, remove screen for inspection. Replace screen if damaged or

plugged.

COMBUSTION DEPOSITS

We recommend that after every 100-300 hours you have an authorized Briggs & Stratton Service Dealer remove combustion deposits from the cylinder, cylinder head, top of piston, and around valves.

AIR COOLING SYSTEM

We recommend that after every 100 hours you have an authorized Briggs & Stratton Service Dealer clean the air cooling system.

Over time debris may accumulate in cylinder cooling fins and cannot be observed without partial engine disassem- bly. For this reason, we recommend that you have an authorized Briggs & Stratton Service Dealer clean the air cooling system per recommended intervals. Equally important is to keep top of engine free from debris.

VALVE CLEARANCE

Check valve clearance yearly. (See Tune-up Specifications on page 16.)
