0 20 Troubleshooting 2 Wrong type of oil If you re not sure what type of oil is in the engine drain it and fill with the correct type Chapter 1 3 Air leak at carburetor intake boots Check and tighten or replace as necessary Chapter 3 4 Float level low Check and adjust if necessary Chapter 3 5 Worn oil pump or clogged oil passages Check oil pressure Chapter 2 Rep ace pump or clean passages as necessary 6 Carbon build up in combustion chambers Use of a fuel additive that will dissolve the adhesive bonding the carbon particles to the piston crowns and chambers is the easiest way to remove the build up Otherwise the cylinder head will have to be removed and decarbonized Chapter 2 24 Lubrication inadequate 1 Engine oil level too low Friction caused by intermittent lac lubrication or from oil that is overworked can cause overheating oil provides a definite cooling function in the engine Check the oil Chapter 1 2 Poor quality engine oil or incorrect viscosity or type Oil is r not only according to viscosity but also according to type Some are not rated high enough tor use in this engine Check the Spe cations section and change to the correct oil Chapter 1 25 Miscellaneous causes 20 Firing incorrect 1 Spark plugs fouled defective or worn out See Chapter 1 for spark plug maintenance 2 Incorrect spark plugs 3 Faulty ignition coil s Chapter 4 21 Fuel air mixture incorrect Modification to exhaust system Most aftermarket exh systems cause the engine to run leaner which make them run ho When installing an accessory exhaust system always reject carburetors Clutch problems 1 Main jet clogged Dirt water and other contaminants can clog the mam jets Clean the fuel tap filter the float bowl area and the jets and carburetor orifices Chapter 3 2 Main jet wrong size The standard jetting is for sea level atmospheric pressure and oxygen content 3 Air cleaner poorly sealed or missing 4 Air cleaner to carburetor boot poorly sealed Look for cracks holes or loose clamps and replace or repair 5 Fuel level too low Adjust the float s Chapter 3 6 Fuel tank air vent obstructed Make sure that the air vent passage in the filler cap is open 7 Carburetor intake manifolds loose Check for cracks breaks tears or loose clamps or bolts Repair or replace the rubber boots Chapter 2 1 Friction plates worn or warped Overhaul the clutch asse Chapter 2 2 Steel plates worn or warped Chapter 2 3 Clutch springs broken or weak Old or heat damaged slipping clutch springs should be replaced with new ones Chapte 4 Worn or warped clutch plates Replace Chapter 2 5 Clutch release mechanism defective Replace any defective Chapter 2 6 Clutch hub or housing unevenly worn This causes impr engagement of the discs Replace the damaged or worn p Chapter 2 22 Compression too high 27 Clutch not disengaging completely 1 Carbon build up in combustion chamber Use of a fuel additive that will dissolve the adhesive bonding the carbon particles to the piston crown and chamber is the easiest way to remove the build up Otherwise the cylinder head will have to be removed and decarbonized Chapter 2 2 Improperly machined head surface or installation of incorrect gasket during engine assembly Check Specifications Chapter 2 1 Sticking cable Inspect and lubricate or replace Chapter 2 2 Clutch plates warped or damaged This will cause clutch d which in turn will cause the machine to creep Overhaul the c assembly Chapter 2 3 Clutch spring tension uneven Usually caused by a sagge broken spring Check and replace the spring Chapter 2 4 Engine oil deteriorated Old thin worn out oil will not pro proper lubrication for the discs causing the clutch to drag Replac oil and filter Chapter 1 5 Engine oil viscosity too high Using a heavier oil recommended in Chapter 1 can cause the plates to stick toge putting a drag on the engine Change to the correct weight oil C ter 1 6 Clutch housing seized on shaft Lack of lubrication severe or damage can cause the housing to seize on the shaft Overhaul clutch and perhaps transmission may be necessary to repai damage Chapter 2 7 Clutch release mechanism defective Worn or damaged rel mechanism parts can stick and fail to apply force to the pressure p Overhaul the release mechanism components Chapter 2 8 Loose clutch hub nut Causes housing and hub misalign putting a drag on the engine Engagement adjustment contin varies Overhaul the clutch assembly Chapter 2 23 Engine load excessive 1 Clutch slipping Can be caused by damaged loose or worn clutch components Refer to Chapter 2 for overhaul procedures 2 Engine oil level too high The addition of too much oil will cause pressurization of the crankcase and inefficient engine operation Check Specifications and drain to proper level Chapter 1 3 Engine oil viscosity too high Using a heavier oil than the one recommended in Chapter 1 can damage the oil pump or lubrication system as well as cause drag on the engine 4 Brakes dragging Usually caused by debris which has entered the brake piston sealing boot or from a warped disc or bent axle Repair as necessary 26 Clutch slipping
