Magnum .46 XLS
Going through a collection of used engines that I acquired in a buy out, I found a Magnum .46 XLS. It appeared to have very little time on it as the piston is not discolored. I bolted it to the front of an old airframe and it started immediately. It ran a little rough, but I got it tweaked up and idling about 2400RPM, good transition and acceptable high end. The problem is that this thing slobbers big time. I mean this thing is spitting fluid, quite a bit of it, at all times. Is this normal in this engine? Will this quit as the engine is run more? All my glow engines slime my airplanes, but this one is ridiculous. I don't even want it on my plane if it continues like this. Does anyone have any idea if this will quit or not?

He must mean it slobbers out the muffler like usual.... but MORE. It slobbers like that when the HS needle is peaked? With stock muffler? Something is effecting the tuning. My Mag. 46 ran better with the larger volume muffler that came with the 52.

Sorry, guys. I meant it slobbers from the muffler outlet. A lot. It is a thick grayish in color fluid that blows all over the landing gear and shop floor. It has one of those exhaust deflectors that is more or less keeping it off the side of the plane.

If it is comming out of the muffler, I would say that is normal. Every two stroke I have will leave a big spot on the floor where I run it from the exhaust. The alcohol will get burned in the running but all the oil in the mix will come out of the muffler. The only thing I can think of that would produce an abundance of fuel out the muffler, is if when being filled, it overflowed into the muffler and the extra fuel in the muffler is blowing out. The other thing could be a higher oil content in your fuel you are using. Other than that, oil comming out of the muffler is good. A new engine when being broken in will have a metalic colored exhaust oil for a while until the parts get broken in good.

RE: Magnum .46 XLS
Well, I give up. I flew the plane yesterday and the engine performed flawlessly. It has really good compression, turns 13K+ at WOT, and idles at 2300+ so I guess I will just run it. I am no stranger to glow engines, and I know they are messy, but this one is ridiculous. It sure keeps the right side landing gear well oiled. I do believe the engine was virtually new, so maybe it will get better as I run it.
