5.2 ENGINE LUBRICATION SYSTEM
The gears of the oil pump are driven by the
engine crankshaft. Pump gears rotate the plunger
shaft in the oil pump. This shaft sends the
lubricating oil into the crankcase to mix with the
mixture of air-fuel flow evenly. The oil enters and
covers the cylinder inner wall, piston surface, and
piston rings.
5.3 CAUTION: Fuel/Oil Ratio
Having enough oil in the engine is very important.
If the oil quantity is too low, the engine will be seriously scratched, likely seize, and possibly not work
again.
When the cylinder wall is scored or scratched, replace the piston, piston rings, and cylinder together.
Check the combustion system and lubrication system carefully.
