Ignitor Identification List

Hi everyone, over the past 27 or so years, my father and I have collected
a fair amount of ignitors. This was so that we could build reproductions of these parts that were so commonly discarded by the original users. It only takes a quick examination of a Low Tension Ignitor to spot the problem, "Too Many Moving Parts"! After a year or two of wear, some designs would begin to malfunction. Farmers, being practical men, were quick to take what steps they saw as necessary to keep the engine going. This most often involved throwing that %#^#@! ignitor as far as he could.

I have, as a result of becoming familiar with a wide variety of Ignitors, found them to be a useful tool in the identification of engines that have lost their badge or are badged under a name other than that of the manufacturer. I have included the Bolt or Stud Centers and the maximum size stud that the mounting holes will accept. These are nominal measurements because if there is one thing I have learned in a quarter century of playing with Old Iron, it is to "Never say Never". As the man says, "Your Mileage May Vary"

Of course if you find a mistake or have some information to add, please contact me at  ignitors@sbcglobal.net
