ORIGINAL: Edge 540
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?
I dont run the engine dry and I dont use after run oil or anything else but I use castor oil
in my fuel. Just make sure you storage your airplane with the propeller pointing up to the ceilling so the remaining fuel in the crankcase runs down to the backplane where it wont hurt anything. Open the carburetor slightly so the mathanol can dry out and evaporate. I think the after run oils are only neccesary for long time storage.
