Adam,
But at $125! Man, I thought for VERY brief moment that this would be cool in my big Tecumseh conversion, but again only for a VERY brief moment. Of course it looks like it's rather large too. Also, $125 is a LOT of spark plugs! What about a control? Seems a standard ignition system would not work? BTW, if my Tecumseh proves to do what I want, I will be contacting you about a muffler if you're interested.
