Harvey......I am using the Dan Price dual ignition head on my engine, (which is a work in progress). One of the mags, an American Bosch, which I bought at Brodhead some time ago, will be driven from the crankshaft and will drive ordinary GM-type plugs.. The other mag is one I bought from Saturn Surplus. It's a brand-new Slick, RIGHT-TURNING mag with an Impulse coupling set up for 15 degrees of lag, which, I'm told, is not enough for a Model-A. (I'm driving it from a modified Ken Perkins side-drive mount, so I needed the right turning mag.) The Saturn mag can be bought with or without ignition leads. I got the leads, which are shielded with 5/8-24 terminations (on both ends). The AS&S catalog lists Champion REJ38 plugs, which are shielded, with 5/8-24 thread and 14 mmX3/8 reach as required by the Price head . They are pricey...$30.00 each. I don't know about heat range. I tend to believe that in a cool-running Model-A one would need a hot plug. I looking at getting four of these for the new Slick to drive. Good luck....Carl Vought----- Original Message -----

Pietenpol-List: shielded cans for spark plugs

Harvey asks->I am looking for the name of these things and where they can be boughtIf I understand you correctly, this should be what you're looking for and Great Plains calls them "shielded spark plug adapters":http://www.greatplainsas.com/scspkplug.htmlThey're not cheap to buy, but once you have them you can use automotive spark plugs at a couple of bucks apiece and they'll pay for themselves in the difference in cost over shielded aircraft plugs. If you're not in a hurry, Great Plains usually has a sale around Christmas and they sometimes list these plug adapters with a 10 or 15% discount.And sorry about the post on insurance through Falcon... I should have clarified that 41CC does run an A65 and had all its test hours flown off already (25, in this case) when I insured it, and that apparently makes all the difference in the world.Oscar ZunigaSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________
