If the engine does not start, then the possible cause is an over-rich air-fuel mixture (too much fuel has entered the combustion chambers of the engine) and getting fuel on the spark plugs.
To start the engine in such a situation, do the following.
1. Fully depress and hold the accelerator pedal.
2. Turn the ignition switch to position «START» (starter) and hold it in this position for up to 10 s. If the engine starts, immediately release the starter switch and the accelerator pedal. If this is not done immediately, the engine speed will increase dramatically.
3. If the engine does not start when the starter is running with the accelerator pedal fully depressed, after a 10-second pause, turn on the starter without pressing the accelerator pedal. Crank the crankshaft with the starter for 10 seconds or until the engine starts.
