Engine - Yamaha MZ300 Owner's Manual

Engine

Perform the following steps to protect the cylinder, pis-
ton ring, etc. from corrosion.
1. Remove the spark plug, pour about one table-
spoon of SAE 10W-30 or 20W-40 motor oil into
the spark plug hole and reinstall the spark plug.
Recoil start the engine by turning over several
times (with ignition off) to coat the cylinder walls
with oil.
2. Pull the recoil starter until you feel compression.
Then stop pulling. (This prevents the cylinder and
valves from rusting).
3. Clean exterior of the multi-purpose engine and
apply a rust inhibitor.
4. Store the multi-purpose engine in a dry, well-ven-
tilated place, with the cover placed over it.
5. The multi-purpose engine must remain in a verti-
cal position when stored, carried or operated.
