Well I'm raising this thread back up because I bought the engine from Wayne and he had it for sale for along time. It sat in tne exact place I put it when it arrived last October I think it was. Work, life in general, and Mr Covid all got in the way of me trying to start it. Well, I went to the post office today and it was a lovely 55 degrees out and bright sunshine! I got home and couldn't bear the thought of going inside so I went to the garage, saw that it was 10 or 15 degrees colder in there than outside, so I opened up the door to let some sunshine and heat in!
There on the pile by where I store my flying gear was the box with the Brodak .049 in it. I thought, "Today is the day!" I looked it over a bit, and opened the needle valve a few turns and tried to blow air through it and didn't feel anything. I turned the needle all the way out and could see a bit of sunlight through the spray bar, gave it another toot of air and the hole looked bigger. I put the needle back in and opened several turns. It had a 7-3 APC prop on it so I left it there. I have a collection of EZ-Just type test stands, grabbed a small one for small engines and mounted it up. I got my starter box out, fuel and syringe and gave it enough fuel in the venturi and exhaust to loosen it up. I hooked up the battery to the glow plug, then hit it with the starter and it barked a little bit. A couple of tries more and it ran the prime out. Then I strapped one of the tanks Wayne sent me with the engine to the test stand and hooked it up with some fuel line. I choked it and applied the starter and it was obviously flooded at that point. Pinched off the fuel line and flipped and cranked it a bit to clear the prime which it did and ran for a few long seconds and ran out the flood. Then I closed the needle, burped it again, opened the needle about 3 or 4 turns and hit it with the starter again. It came to life and settled into a rich four stroke. I leaned it out a bit to a higher four stroke seating and it needled vary nicely. It ran out the tank, (maybe an ounce) and filled the tank for another try. This time i didn't choke it and just hit it with the started and it fired to life right away. I needled it up to where it was breaking back and forth from 4 to 2 stroke and back again and put a tach on it and saw 12,800 RPM with the 7-3 APC. I thought that was pretty healthy myself. It rand that tank dry so I proceeded to clean things up and put stuff away because the sun had gone back behind the house and it was breezy and getting cooler.
One thing I noticed while it was running the second time , was really small air bubbles coming out where the post f the glow plug went into the ceramic seal. This was barely noticeable, but I could blow or wipe them away and they would return. I'm not sure what type of plug it is but may have been part of Wayne's problem. I also think there may have been some sort of blockage in the spray bar. I will replace the glow plug once I get around to it and see if I have something hanging in the garage to mount it on and fly it. If it happens to match the tank mount for a Norvel or the red tank mount for a Cox TeeDee .049 that may make this job easier. I don't know the exact cause of Wayne's problems But think it was just a series of really small events and happened to solve them right away.
Type at you later,
