Troubleshooting from Kawasaki TJ27D workshop manual
Pulling recoil starter grip would not cause enough compression-Wear in piston, Wear in piston ring, Wear or deformation of cylinder bore, Poor tightening of cylinder and spark plug.
After making several starting attempts, it is found, on removing spark plug, that electrodes are still dry-No fuel in fuel tank, Clogging of dust or entry of air in fuel pipe, Clogged fuel tank cap air vent and breather, Foul fuel filter in fuel tank, Air entering at gasket fitted to carburetor flange, Clogged carburetor needle jet or main jet.
After making several starting attempts, it is found, on removing spark plug, that electrodes are excessively wet-Faulty starter button pushing (ln summer, or when the engine is warm, starter button-pushing gives too rich mixture), Overflow of fuel from carburetor, Clogged air cleaner.
On removing the spark plug, moisture condensed on spark plug electrodes-Mixture of water into fuel, Deterioration in fuel because of poor long-term storage, Use of fuel other than designated.
Make spark check. No spark but spark appears on spark plug replaced-Electrodes are burned and damaged to cause the too wide gap, Much carbon bridging electrodes gap, Small foreign matter being caught between electrodes, Faulty insulation of electrodes.
No spark in any spark plug, but spark appears when the end of high tension cord is touched to engine block-Faulty contacting at spark, plug cap.
No fuel drains into the return pipe in spite of several priming operation-Clogging in fuel tube at the inlet side, Broken tube at the inlet side, Air leakage from joint part of the fuel tube at
inlet side, Adhesion of dust to check valve of priming pump, Broken check valve of priming pump or damaged seat surface of pump cover, Air leakage from fitting area of priming pump, Broken priming pump, Air leakage from main check valve, Loosen main diaphragm cover, Broken main diaphragm.
Fuel drains into the return pipe by priming operation, but engine does not start-Clogged air filter, Clogged needle jet, Overflow of fuel from needle jet to the venturi of carburetor.
After starting, engine revolution does not continue-Clogged pulse passage, Improper height of control lever.
No spark or very weak spark at the end of high tension on cord-Engine switch lead wire is jammed, Short circuit in engine switch, Recoil starter revolution is lower than that igniter begins to work, Wiring of coil coming short circuited or disconnect, Engine switch lead wire is jammed, Flywheel demagnetized.
When throttle valve is opened gradually, revolution speed drops at some position or engine stops, Clogging in carburetor inside, Foul fuel filter, Faulty carburetor gasket, Incomplete fitting of carburetor.
When spark test of spark plug is made with recoil starter rope pulled, spark appears very week-Faulty insulation of spark plug, Foul electrodes, Faulty magneto, Faulty ignition coil.
Loaded operation causes revolution fluctuation with big frequency-Clogged fuel tank cap air vent and breather, Dust clogging in or entry of air into fuel pipe or carburetor.
Unstable idling and the running does not continue-Air entering engine through the fitting part of carburetor, Too low idling speed (rpm), Clogged main check valve, Clogged needle jet or main jet, Improper height of control lever.
Engine does not accelerate in spite of opening throttle valve-Clogged air filter, Clogging in fuel tube at inlet side, Fuel passage or pulse passage of fuel pump is clogged, Clogged needle jet or main jet, Clogged main check valve, Improper height of control lever.
Unstable revolution at high speed-Clogged air filter, Clogged in fuel tube at inlet side, Fuel passage or pulse passage of fuel pump is clogged, Clogged needle jet or main jet, Clogged main check valve, Improper height of control lever.
Same as “Hard Starting”-Same as “Hard Starting”.
Engine overheated-Clogged air cleaner, Carbon deposit inside combustion chamber, Inappropriate mixing ratio (too little oil), Broken cooling fan blade, Dirt or dust attached to cooling fins of cylinder, Grass or dirt attached to cooling air passage and flywheel blade.
Thick smoke issues from exhaust port-Same as “Hard Starting”, Carbon deposit narrows
exhaust passage and muffler, Excessive oil mixed.
Engine knocking-Inferior fuel.
Abnormal Engine Noises
Piston Slapping-Cylinder and piston ring wear, Wear and/or deformation in piston, Carbon deposit inside combustion chamber, Wear in piston pin and connecting rod small end bearing, Wear in piston and piston pin.
Connecting rod noise-Wear in large and small end bearings.
Surging-Foul air cleaner, Dust clogging in or air entry into fuel pipe, Clogged fuel tank cap air vent and breather, Clogged carburetor.
Fuel Leakage from Carburetor
Fuel leak from carburetor-Foreign matter attached to needle valve and/or valve seat, Correction or wear in needle valve and/or valve seat, Poor tightening of diaphragm gasket.
Excessive Fuel Consumption
Same as “Hard Starting”-Poor compression.
Sufficient compression but excessive fuel consumption-Too rich fuel mixture, Inferior fuel, Foul air cleaner, Too high idling speed.
Same as “Fuel Leakage from Carburetor”-Same as “Fuel Leakage from Carburetor”.
Engine Stops during Operation
Difficulty in cranking, or seizure-Excessively lean fuel mixture (too little fuel), Inferior lubricating oil mixed, Excessive carbon deposit in combustion chamber, Dust accumulation on cooling fins of the cylinder.
Cranking is easy-Faulty spark plug, Faulty magneto, Looseness in connections, Faulty ignition coil.
