Re: What does it mean when
As ACC said, replace the plugs, and check it again on a dark night. Do not run this motor until you can, also.<br /><br />This is because the arcing (or more acurately, lack of an ability for the potential to find ground thru the plug), willl eventually wipe-out the CD pack or coils.<br />If the plug fouls, or the plug wire's insulation breaks-down, the arc of electricty will;<br /><br />1.Develope a route to ground thu the insulation material, breaking it down into a carbon path to ground. This will ruin the plug wire ,or whatever device is arcing to ground (CD pack or coil subrates ect).<br /><br />2. require higher voltage potential to complete the path to ground, which can short-out the CD transistor or coil windings.<br /><br />So it's a good thing you found it ,hopefully in time to fix itwith a plug (as opposed to plug wires and cd packs).
