    "I read one of Joes' Reeves earlier posts about checking spark and the distances the spark should jump. I had been using spark plugs to check for spark and I now understand why this doesn't work very well. The do it yourself tester is a great idea (especially for testing multiple cylinders) and I intend to build one soon. In the mean time, I came across a inexpensive commercial model available at car quest auto stores that might be of interest. The tester is quite easy to accurately adjust for any gap up to 1 inch. It has an alligator clip on one side and a spark plug terminal at the other end. I had never seen this tool before and thought some of you might be interested. It is made by Lisle and the car quest number is STL 50850. I believe the cost was $7.00. spark tester
