RE: New Engine Break In
I guess we all come to our own theories as a result of our experiences, and what we read and hear from others. I went flying today also, the plane flew great, and the engine purred like a kitten. Guess we'll just have to see how long it lasts. I fattened up the low end a tad, so now it 4 cycles like Gregs, and im gunna try that for a while. Sounds funny when I slow down, but it still runs smooth. It seems to take about 1 minute of warmup before it will transition perfect, and another minute of flying before it really gets with the program, so I don't think it running hot, it takes too long to warm up to be running hot. It's way more cold blooded than my Saito's. I have had the plug out when fitting the cowl, and it looks perfect. The center insulator is a nice tan color, and the plug is clean. As a professional mechanic, I can tell if an engine was running hot just by inspecting the plug, and my plug says no. I will continue to inspect it from time to time though.
