Andy,

I may take you up on that plug converter sometime down the road. Right now I'm going nuts fixing up the house for some relatives coming in late July.

Have you ever tried making a "Blind" plug adapter so the glo-plug bottoms out against the bottom of the adapter? It would sure keep the combustion chamber clean. All the piston would see is a hole for the element. Just a thought.

Martin, those OS, Magnum and Thunder Tiger .10's will probably all take the OS .10 diesel conversion heads. I'd like to see if it also works on an ASP .12.
