I worked a month in a motorcycle shop, one time we had an old Arctic Cat JAG in the shop. He told me to start it and ride it out of the shop. It started after many pulls and then stopped.
I told him that it probably fouled a sparkplug, so I figured we`d have to put new plugs in it, but then he told me about the propane tricks. (I hadn`t heard about it before).
I used a welding torch to heat it up and the plug was fine after that.
However, he told me that it wouldn`t work with a lighter.. it would only make it worse because there would be more "carbon" from the lighter flame.
But maybe he`s wrong then.. .
Oh, what should I use for cleaning a sparkplug, or is it stupid to clean them?. Guess they wount fire any better if it`s shiny.. ?.
How will a fixed fouled plug last as long as a new plug?.
