I have an SPE 26cc. I have about a gallon through it, but I find that it seems to be telling me it needs leaned out. Of the past 4 flights, I had to lean low end twice just a touch for it to run right, and today had to lean high end. I have heard guys with other brand 26cc's say they have never touched their needle valves. The engine runs great, just wondering if its normal for these engines to tell you when they are ready, because that is what seems to be happening.
