TROUBLESHOOTING

Low power output

When turning
throttle greater, rising of speed responds slowly or speed is decreased or engine stops running.| Ignition system| Incorrect ignition time| Readjust ignition advance angle
Fuel supply system| Air in fuel line or fuel line clogged| Expel air or dredge fuel line
Main jet is not adjust properly| Readjust
Metering jet and main jet clogged in carburetor| Clean and blow to get through
Fuel cock is clogged up| Clean and replace damaged part
Too much carbon fouling
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

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

Engine is excessively hot

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

parts
Tie rod or piston pin and piston pin hole is worn| Replace the worn parts

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
