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 dealer clean the cooling system per recommended intervals (see “Maintenance Schedule” on page 14). Equally important is to keep top of engine free from debris. See “Cleaning”.
