I'm new to glow engines, but I have had the help of an "old hand" in sorting this problem out. I flew my new TT .28 today on a SpadStik. She would start and run through transition easily enough, but any time she was tipped up, she'd die. My buddy made a number of adjustments and she seemed to be OK.
Of course, as soon as I had her up and flying...on a small rise in altitude, she died out again. I am going to re-route the fuel line so it stays more horizontal. Right now, the fuel line rises over the engine bulkhead and back down to the input fitting That rise is only about 3/4 of an inch. Could that be the issue? When she dies out, the fuel line is still FULL??? I noticed that she doesn't draw much in the way of fuel, as compared to my other engine. When I close off the intake port and hand crank the engine, the fuel doesn't rush forward, like it does on my other .46 engine??
Additionally, my buddy noticed that we have oil coming out of the front bearings. Could this be a factor and what might I do about it? This engine has only been run a half dozen times on my bench, and now with two flights, it doesn't seem to be working very well. Any and all help appreciated.
P.s. I also own a OS.46AX, which exhibits none of these issues.
