DLE-20cc Unreliable
All help will be appreciated. This motor starts and runs great on the bench. Just will not keep running in the air. For example: Adjusted the low and high needles so it transitions well. Runs good at high speed and idles fairly well - seems to like idling - maybe 1800 rpm, but at idle slowly slows down until it settles at maybe 500 rpm slower. Crank it up and life is good. Taxi out to the runway, makes sure it's warm, run it up a few times - all is good. Take off, fly around - do a couple of rolls, loops etc - going well for 4 - 5 minutes, throttle back to a high idle, set up for landing and it quits. - Dead stick landing. 3 times in a row.
Then did similar thing, tried to fly around on edge for a half turn, leveled it out - and it quit.
So far have replaced the fuel - always using e-free fuel with red-line 2-cycle oil, new fuel tank, carb a while ago, 15 x 8 prop, fiddled and diddled with the low and high needles - seems like always the same result. Next, I'll replace the ignition and see if something funky going on there. Otherwise, I'll replace the carb again.
Anyone hove a suffered through a similar situation? Suggest a solution? PETE
