in combusting chamber| Clear away
Too much carbon fouling in muffler and exhaust pipe| Clear away
Air cleaner is clogged up| Clean air cleaner element
Intake pipe is leaking| Repair or replace
Poor compression| Piston or cylinder or piston ring is worn| Replace the worn
Air leakage from the surface by which cylinder block contacting with cylinder
head.| Replace cylinder gasket
Too big or too small valve clearance| Readjust
Valve tightness is poor| Repair
Engine can not run smoothly
Symptom | Cause Analysis | Troubleshooting |
---|---|---|
Engien is pinking | Piston,cylinder or piston ring is worn excessively | Replace |
the worn parts
Piston pin and piston pin hole are worn excessively| Replace piston or piston
pin
Tie rod small head is worn excessively| Replace tie rod
Roller bearing for crankshaft is worn| Replace roller bearing
Abnormal combustion| Engine is too hot| Shoot trouble
Too much carbon fouling in combustion chamber| Clear away
Improper gasoline class or low gasoline quality| Replace with qualified
gasoline
Engine can not start because of
spark lacking| There is water in floater room| Clean
Improper spark plug electrode clearance| Adjust
Incorrect ignition time| Readjust
Something failed with induced coil,and so on| Check and replace damaged parts.
Stop suddenly when running
Symptom | Cause Analysis | Troubleshooting |
---|---|---|
Stop suddenly when running | Fuel supply system | Fuel is used up |
Carburetor is clogged | Check fuel line and dredge | |
Float is leaking | Repair | |
Needle valve sticks | Dismantle float bowl and shoot trouble | |
Ignition system | Spark plug is struck through, or shortcircuited by carbon | |
fouling | Replace spark plug | |
Side electrode of spark plug is dropped out | Replace spark plug | |
High-voltage wire is dropped out | Weld on | |
Ignition coil is struck through to be short-circuited | Replace ignition coil R | |
Parking wire is located on engine body | Find out meeting and insulate | |
Others | Cylinder is pulled damage | |
and valve is dropped out | Repair or replace damaged parts |
Engine is excessively hot
Symptom | Cause Analysis | Troubleshooting |
---|---|---|
Engine is excessively hot | Improper ignition time | Adjust ignition advance |
angle properly
Insufficient fuel supply| Refill sufficient engine oil
Exhaust pipe is clogged| Dredge exhaust pipe
Flow guard is leaking| Repair leakages
Dirt or something else jams among air cooling fins| Clear away dirt or
something alike
Cooling fan is loosen and malfuction| Reinstall properly
Tie rod deformation makes piston and cylinder bushing side wear| Replace tie
rod
Cylinder or piston or piston ring is worn resulting in air flow between
cylinder and crankcase| Replace the worn parts
Improper adjustment of engine speed| Readjust engine speed
Excessive rotational speed occurs| Readjust speed regulator
Crankshaft main bearing is burnt out| Replace main bearing
NOTE:
The engine should be operated under certain temperature range.
Generally it is permitted that temperature at the flow guard outlet between
80~110 while the temperature of the crankcase under the magneto motor around
60. If temperature surpasses upper limit, it is an indication that the engine
is excessive hot.
Abnormal noise occurs when engine is running
Symptom | Cause Analysis | Troubleshooting |
---|---|---|
Noise of beating | Piston or piston ring or cylinder is worn | Replace the worn |
parts
Tie rod or piston pin and piston pin hole is worn| Replace the worn parts
Crankshaft main bearing is worn| Replace
Piston ring is broken| Replace
Metal-beating noise in
abnormal combustion| Too much carbon fouling in combustionchamber| Clear away
carbon fouling
Too small electrodes clearance of spark plug properly| Adjust electrodes
clearance
Engine is flooded with fuel| Check relating parts such as carburetor
Improper fuel class| Replace fuel
Engine is excessively hot| Shoot trouble
Others| Improper valve clearance| Readjust valve clearance properly
Fly wheel is not connected to crankshaft tightly| Connect tightly
