Yeah Art, ma faute, I wasn't clear. Sorry. The device at the right has a flat bottomed CP with a glow plug installed. It was used on diesel fuel and the glow plug was energized to see if that would help a cold start without having to adjust the compression. And to see if the glow element, although not glowing, might provide a hotspot to aid in ignition of the diesel fuel.

The contra-piston on the left, goes into the same device. Note the slight trumpet shape and the glow plug is of the turbo variety.

Hey, Downunder,

Come to think of it, my limp synapses are struggling to straighten up and tell me that you had mentioned that somewhere, sometime. I marvel that you were able to do it.

And WAIT a minute. No such thing as too much power, is there?

But you've given me an idea for ANOTHER test.

I gather nitromethane is hard to come by "down" there? As is ether? Izzat Howard's fault?

The first picture is of the subject matter.

The second is an attempt to post a picture that the PM function can't handle. I'm trying to get some threaded rod the same size as the threads on the Norvel head clamps.
