I am just getting into RC airplanes and have an engine question. I have a two stroke .25LA OS engine and have been trying to break it in. I have run it about 5 or 6 times so far. I started it out very rich for the first 3 or 4 runs. It seems to be gaining in power and smoothness each time it is run now, but it doesnt seem to care for being run as rich as it first did.

Just wondering if this is normal for a break-in of this type engine.

Thanks.

Actually, that sounds like a perfectly normal behavior for an engine as it breaks in. Once the engine starts to settle in, it won't like being run as richly as when it was new. It sounds like your .25 LA is breaking in nicely!
