Since a brief tion will often locate the trouble before the is reached, this should be done first. The should be opened only when it is certain that the ignition spark produced is unsatisfactory. This condition may be determined by ignition spark tests in the field.

With a properly adjusted spark plug in good tion, the ignition spark should be strong enc bridge a short gap in addition to the actual plug discharge. This may be determined by holding the end of the ignition cable not more than 1/8 inch away from the spark plug terminal with the engine running. The engine should not this is done.
