I finally tracked down just the needle valve and the one gasket I am sure to need. $14.39 total with shipping and tax. At least I think it is right. As worst I wasted $14.39.

It does appear to be a Techumseh engine but there is no tag on the engine itself. I would like to find the entire carb if possible if it is a direct fit. I had seen the Ebay needle valve and was hesitating ordered from multiple sources just to no avoid three shipping charges.
There is lawn mower repair place just three blocks from the very center of downtown Edmond. I was there 20 years ago and the old man running it was a long time mower repair guy. Likely he would have "gone to the back" and handed me a few parts that I needed for cheap. Now he is gone and I think it is his nephew runs the place. He is not the man his uncle was. He seems to hate little orders like mine. I am just stubborn enough to figure out a fix for my old edger and spend way more time and effort on keeping it running than just giving up and getting some new edger.
