3.7 compress pressure
Remark:
When finish adjust
Valve Clearance, then
measure the
compress pressure.
1. For running few mins.
2. Remove spark plug.
3. Use manometer and adapter for measure.

Measure:
Measure pressure you need pull the starter when the pressure finger stop, read the NO..
The standard:400-600kpa(4-6kg/cm3,57-85 psi )
Waring:
When start engine, spark plug need connect for ground, that no spark.
Measure step(At lowest level):
dripping little engine oil for cylinder, then mesure the compress pressure.
Reading Estimate
Low than no oil Cylinder,piston or piston rings are
wear and tear.
The same with no oil Piston, piston rings,
valve,Cylinder gasket fail.
Or need adjust valve clearance.
Measure step(At high level):
Check cylinder, valve and piston whether or not have carbon dirty.
Build in the spark plug:
