elden i knew what it was just couldn't spell it:shrug: thanksBob:
The grill lighter units are called "piezoelectric spark pumps". The word is pronounced, pie-eez-oh electric. These guys get their spark from a special man made crystal that gives off a Voltage pulse when you bend, then release it.
Briggs & Stratton (I think) used them for a short time on their engines for ignition but I suppose that out in the real world of dirt, heat, etc. they didn't hold up. I think all were recalled.
They don't put out quite as big a spark as a magneto but, if you do it right, they should work fine on slow engines and away from most of the heat.
Take care - Elden
Back in the day (~2002) there was informational text at the top of this .jpg. I have no idea where I got the image from, but it said: "The button on the igniter has to travel 10mm, which is done with a lever operated by the downward pull of the moving core. A reduction of about 4 1/2 to 1 is required because of the limited travel of the core. This system has unlimited application because of the simplicity of operation. For instance, a machine with a magneto missing it could be set up to operate off a cam. As for the life of the igniter I do not know but it has been running my 3 H.P. Challenge for some time & still going strong. At a cost of $3 it is worth while to get your machine running."
