battery Chapter 8 4 Starter motor defective Make sure the wiring to the starter is secure Make sure the starter relay clicks when the start button is pushed If the relay clicks then the fault is in the wiring or motor 5 Starter relay faulty Check it according to the procedure in Chapters 6 Starter button not contacting The contacts could be wet corroded or dirty Disassemble and clean the switch Chapter 8 7 Wiring open or shorted Check all wiring connections and harnesses to make sure that they are dry tight and not corroded Also check for broken or frayed wires that can cause a short to ground see wiring diagrams Chapter 8 8 Ignition switch defective Check the switch according to the procedure in Chapter 8 Replace the switch with a new one if it is defective 9 Engine kill switch defective Check for wet dirty or corroded contacts Clean or replace the switch as necessary Chapter 8 10 Faulty starter lockout switch if equipped Check the wiring to the switch and the switch itself

Inspect and replace the damaged parts Chapter 2 3 Starter works but engine won t turn over seized Seized engine caused by one or more internally damaged components Failure due to wear abuse or lack of lubrication Damage can include seized valves valve lifters camshaft pistcns crankshaft connecting rod bearings or transmission gears or bearings Refer to Chapter 2 for engine disassembly 4 No fuel flow 1 No fuel in tank 2 Fuel tap vacuum hose broken or disconnected 3 Tank cap air vent obstructed Usually caused by dirt or water Remove it and clean the cap vent hole 4 Fuel tap clogged Remove the tap and clean it and the filter Chapter 1 5 Fuel line clogged Pull the fuel line loose and carefully blow through it 6 Inlet needle valve clogged For all of the valves to be clogged either a very bad batch of fuel with an unusual additive has been used or some other foreign material has entered the tank Many times after a machine has been stored for many months without running the fuel turns to a varnish like liquid and forms deposits on the inlet needle valves and jets The carburetors should be removed and overhauled if draining the float bowls doesn t solve the problem 5 Engine flooded 1 Float level too high Check and adjust as described in Chapter 3 2 Inlet needle valve worn or stuck open A piece of dirt rust or other 0 17 debris can cause the inlet needle to seat improperly causing excess fuel to be admitted to the float bowl In this case the float chamber should be cleaned and the needle and seat inspected If the needle and seat are worn then the leaking will persist and the parts should be replaced with new ones Chapter 3 3 Starting technique incorrect Under normal circumstances i e if all the carburetor functions are sound the machine should start with little or no throttle When the engine is cold the choke should be operated and the engine started without opening the throttle When the engine is at operating temperature only a very slight amount of throttle should be necessary If the engine is flooded turn the fuel tap off and hold the throttle open while cranking the engine This will allow additional air to reach the cylinders Remember to turn the fuel tap back on after the engine starts 6 No spark or weak spark 1 Ignition switch Off 2 Engine kill switch turned to the Off position 3 Battery voltage low Check and recharge battery as necessary Chapter 8 4 Spark plug dirty defective or wom out Locate reason for fouled plug s using spark plug condition chart and follow the plug maintenance procedures in Chapter 1 5 Spark plug cap or secondary HT wiring faulty Check condition Replace either or both components if cracks or deterioration are evident Chapter 4 6 Spark plug cap not making good contact Make sure that the plug cap fits snugly overthe plug end 7 Igniter defective Check the unit referring to Chapter 4 for details 8 Pickup coil s defective Check the unit s referring to Chapter 4 for details 9 Ignition coii s defective Check the coils referring to Chapter 4 10 Ignition or kill switch shorted This is usually caused by water corrosion damage or excessive wear The switches can be disassembled and cleaned with electrical contact cleaner If cleaning does not help replace the switches Chapter 8 11 Wiring shorted or broken between a Ignition switch and engine kill switch or blown fuse b Igniter and engine kill switch c Igniter and ignition coil d Ignition coil and plug e Igniter and pickup coil s Make sure that all wiring connections are clean dry and tight Look for chafed and broken wires Chapters 4 and 8 7 Compression low 1 Spark plug loose Remove the plug and inspect the threads Reinstall and tighten to the specified torque Chapter 1 2 Cylinder head not sufficiently tightened down If the cylinder head is suspected of being loose then there s a chance that the gasket or head is damaged if the problem has persisted for any length of time The head nuts should be tightened to the proper torque in the correct sequence Chapter 2 3 Improper valve clearance This means that the valve is not closing completely and compression pressure is leaking past the valve Check and adjust the valve clearances Chapter 1 4 Cylinder and or piston worn Excessive wear will cause compression pressure to leak past the rings This is usually accompanied by worn rings as well A top end overhaul is necessary Chapter 2 5 Piston rings worn weak broken or sticking Broken or sticking piston rings usually indicate a lubrication or carburetion p oblem that causes excess carbon deposits or seizures to form on the pistons and rings Top end overhaul is necessary Chapter 2
