I have a supertigre 90 that is about at the end of the break in stage. Just less than a gallon through it. I have only flown it for a summer. (very sparingly since it still has less than a gallon) I put it in the basement for the winter and I got it out today. I took off the carb to adjust something outside the cowl, and you can clearly see a redish splotch on the forward crank shaft. [:@] It is not raised or rough, but I was surprised to find rust already. I try to take care of my engines, and I usually put a little piece of paper towel in the carb to keep air out.
I dont think it will make a bit of difference, but I was kinda surprised. What can I do to prevent this in the future? I'm running recommended prop and fuel.
Also, the baffle somehow came lose inside the muffler. This is a one piece unit! It rattles at idle. There is no crash damage, not even a nose over yet. Is there any fix for this?
