Too low cylinder pressure may cause the
following:
Excessive wear to cylinder;
Wear to piston or piston ring;
Blockage of piston ring in groove;
Close valve seat;
Damage to cylinder lining or faults of
other parts.
Measure engine compression pressure:
1. Warm up engine.
2. Ensure full charging of battery.
3. Remove the relevant plastic parts and
accessories from the outside of the
engine.
4. Dismantle spark plugs.
5. At spark plug hole, install cylinder
pressure meter.
6. Press button of start for several seconds.
Record indication of maximum cylinder
pressure.
Check the engine oil pressure periodically.
This will give a good indication of the
condition of the moving parts. The engine
oil pressure test should be done with a
warm engine 90℃ and the recommended
oil.
