Chris, Per, Kirk, Brian, Achim, Art, Rudy, and Dave; thanks for your kind comments. They are appreciated and were needed.
I’m about done with this model. You may recall that I’m building it for a friend, and a while back I had told him that it wasn’t running and if he didn’t want it (why would he?), I was going to strip it of parts and toss the rest in the trash. (I had completed it and then spent over a month, trying to get it to run dependably and I was pretty disgusted with it).
He encouraged me not to do so and stated he was still interested. That saved it from the scrap bin… and a day or two later I got one more idea to try in order to produce dependable ignition.
I re-designed and built the igniter one-more-time and this last version, though it departs somewhat aesthetically from the full size igniter, produces dependable ignition.
I’ve had this model on the bench for a few days or so and now it will start, sometimes with a flick of the flywheel, sometimes more reluctantly with an electric drill; but it will start and run on my schedule, not when it wants too. Though the governor does not control its speed (which is a disappointment but I’m thinking is a lost cause) I’m calling the model done and am ready to hand it over, with some expectation that it will run dependably for its soon-to-be new owner.
