16.11.3.1. Check of spark plugs

 PERFORMANCE ORDER

When one of spark plugs does not work, the engine idling strongly vibrates – "troit".

On the engine idling serially we disconnect high-voltage wires from spark plugs.

It is necessary to do it in a rubber glove or having wound a wire (in several layers) with dry rags. At removal of wires from the working candles the engine loses turns or even becomes deaf.
