feeler gauge वाक्य

For years, I carried a feeler gauge and the screwdriver I needed to reset the points on a rear-engine VW, just so I could stop whenever I saw a broken-down bug and reset the points so the hapless occupants could be on their way again.
However it is necessary to check periodically the maximum opening gap of the breaker ( s ), using a feeler gauge, since this mechanical adjustment affects the " dwell " time during which the coil charges, and breakers should be re-dressed or replaced when they have become pitted by electric arcing.
