7. STORAGE OF ENGINE
Should the engine be stored for a long period, Please do the following:
①Drain off the fuel in tank and oil in crankcase;
②Remove the spark plug, add about 2~3 cc. of engine oil into the cylinder, and reinstall the spark plug. Pull the recoil
until you feel compression. At this time, both the inlet and exhaust valves are closed to prevent the engine chamber
from rusting;
③Clean the surface of engine with clean cotton;
④ Store the engine in a dry and dust free area.
⑤Electric starter: disconnect the battery, charge the battery once every mouth.
8. TROUBLE SHOOTING
Starting failure:
① Is ignition normal?
• Is engine switch turned to “ON” position?
• Remove the spark plug, clean or replace it.
② Is compression sufficient?
• Confirm by pulling the starter handle slowly. When compression is insufficient, check the spark plug. If it is loose,
tighten.
③ Is fuel flowing into the combustion chamber?
• Is fuel valve open?
• Close the choke lever and pull the starter handle several times, then remove the spark plug. When the tip of spark plug
is wet, it is OK.
• If fuel is not flowing, check fuel strainer for clogging.
• When engine does not start though fuel is flowing, replace fuel with new fuel.
When the engine does not start in spite of above inspections, call GOSS Power Products @ 1-877-270-7772.
