RE: DLE 20 Break In procedure?
Ever heard the term TLDR? That thread was just that. After the 4th page of hey when can I get one, or need more Mt Dew, I gave up reading it.
I did read the newbie thread, and it was helpful, didnt really tell me anything I didnt already know.
The one thing I needed verification on was the bench running, I read somewhere not to do it, and elsewhere to do it. Basically confirmed to run it in the plane in the air, mid throttle or so, very little WOT if possible for the first few gallons. As with any engine, proper break in techniques provide long engine life. The Glow engines run on a bench with a certain prop at certain speeds for set amount of time before mounting in a plane is one technique that gives a long engine life, but is NOT the same technique used for the gas engine, and that is what I needed to confirm. Treat it the same as I would a new car, drive lightly the first 500 miles, light throttle, no hard acceleration, etc. and that appears to be the same for these gas engines.
When it comes to the actual engine itself, these are really just mini versions of the one on the end of a weed wacker, or a snow thrower, or even on a motorbike, but have less cooling, thinner crankcase and cylinders, and overall lighter weight materials, so more delicate, but the carb works pretty much the same. I've been working on them for a good 25 years now, quite familiar with 2 cycle gasoline engines, but never had the chance to mess with these little guys.
One thing not mentioned in the newbie thread, and I feel it is important, ALWAYS drain the tank and empty the carb when done flying for any length of time if Ethanol is present in your gas, the ethanol will eat the gaskets and dry out the fuel lines. I made the mistake of having a half tank of fuel in my weed wacker left over for the winter, it sat for about 7 months with that fuel in it and when I went to use it, the gas poured out the tank where the fuel lines are and I found they had disintegrated from the Ethanol. So much for using sta-bil. Gas was still good, no varnish, but no fuel lines either.
