Troubleshooting
ENGINE TURNS OVER BUT FAILS TO START
1. Ignition switch, engine cut-out switch or tether cord is OFF position.
– Place all the switches to ON position.
2. Faulty fuse on v-800 models
– Check F4 fuse on v-800 models.
3. Mixture not rich enough to start cold engine.
– Check fuel tank and check starting procedure, particularly use of the choke
or primer.
4. Flooded engine (spark plug wet when removed).
– Do not choke. Remove wet spark plug, turn ignition switch to OFF and
crank engine several times. Install clean, dry spark plug. Start engine fol-
lowing usual starting procedure. If engine continues to flood, see an autho-
rized Lynx dealer. SDI opening the throttle fully during cranking will switch
off the fuel.
5. No fuel to the engine (spark plug dry when removed).
– Check fuel tank level; turn fuel valve on if applicable; check fuel filter; re-
place if clogged; check condition of fuel and impulse lines and their con-
nections. A failure of the fuel pump or carburetor has occured; contact an
authorized Lynx dealer.
6. Spark plug/ignition (no spark).
– Remove spark plug (s) then reconnect to spark cap. Check that engine cut-
out switch is at the ON position and the tether cut-out cord cap is snapped
over the receptacle. Start engine with spark plug (s) grounded to engine
away from spark plug hole. If trouble persists, contact an authorized Lynx
dealer.
7. Engine compression.
– As the engine is pulled over with the rewind starter, ”cycles” of resistance
should be felt as piston goes past top dead center (each piston on multi-
cylinder engines). If no pulsating resistance is felt, it suggests a major loss
of compression. Contact an authorized Lynx dealer.
ENGINE LACKS ACCELERATION OR POWER
1. Fouled or defective spark plug.
– Check item ”Engine turns over but fails to start”.
2. Lack of fuel to engine.
– See item ”Engine turns over but fails to start”.
3. Carburetor adjustments.
– Contact an authorized Lynx dealer.
4. Drive belt worn too thin.
– If the drive belt has lost more than 3 mm of its original width, it will affect
vehicle performance.
5. Drive and driven pulleys require servicing.
– Contact an authorized Lynx dealer.
