Sport 10, I had a LEO 46. It was an earler one. I had nothing but trouble with it. I will state that I am a professional mechanic by trade. So figuring out how to make an engine run is fairly easy for me. I have gotten some real stinkers to run.

The carburetor was that bad it could not be tutned even with pliers. It had to be replaced. It was under warranty. The second carb still stuck. I had to polish the barrel and the bore to get it to work. It does work great now, I keep it for a spare. The engine just could not be tuned worth a damn. It only had about 25 flights on it before I got mad at it and pulled it from my Tiger II. I finally dissasembled it and inspected it. I did find the problem. The pin on the crank that the lower connecting rod attatches to the crank was shot. The bronze bushing was fine. The pin was just eroded, scored away. Allowing the piston/rod to have the timing go out with the porting. basicly it flopped up and down enough the engine's vacume and timing were way out. I could not get a crank for it. The crank had been changed in subsequent runs and would not fit. That was what I was told when asking about it. The pin's heat treatment was either botched, or not done. Several other fliers in my area also had similar Quality control issues. mine was not a single case.

I Will admit several people had good luck with thiers. But the amount of problems with others lead me to my conclusion. I hope that the QC has gotten better. I hope they have. So if anyone has good stories to tell please prove me wrong. I would not mind if LEO got it's act together. It would be nice to have yet another low cost decent option.

So guys go ahead, tell the stories of your good expieriences with these engines. I would like to know how things are now.
