"I'm well aware of the need to check for spark and am equally aware that holding the plug to the block is a poor way to do that. Joe, I see you use the figure of 7/16" a lot and I'm wondering how I could set up such a tester. My initial thoughts involve a piece of wood and a couple of finishing nails driven in and bent over to get the heads 7/16" apart. Then could I just take a piece of wire from the plug boot to a nail and a wire from the other nail back to the block?? I'm wondering what your rig looks like. Seems too simple to work, so I thought I'd ask...

Spark Tester - Home Made
(J. Reeves)

A spark tester can be made with a piece of 1x4 or 1x6, drive a couple nails through it, then bend the pointed ends at a right angle. You can then adjust the gap by simply twisting the nail(s). Solder a spark plug wire to one which you can connect to the spark plug boots, and a ground wire of some kind to the other to connect to the powerhead somewhere.

Using the above, one could easily build a spark tester whereas they could connect 2, 4, 6, or 8 cylinders all at one time. The ground nail being straight up, the others being bent, aimed at the ground nail. A typical 4 cylinder tester follows:


..........X1..........X2

.................X..(grd)

..........X3..........X4"

John - This tester of Joe's really works. I'm waiting to get my hands on a piece of scrap Paxolin to make up a more permanent and robust version. Its a very worthwhile tool to have around.
