I broke a cam gear and even a tooth off the crankshaft as well.
How in the hell did that happen?
Upon disassembly, everything was nice and wet with lubricant. Dang. 70 dollars of damage and I have no idea why.
I agree. I was flying my 220 and it was running great. Then it just quit in mid flight and I had to dead stick it in. Thought maybe it needed some adjustment, but when I tried to start it again the prop just spun freely. I took the engine apart and found I had lost 4 teeth on the cam gear???? My 220 has been sittting on the bench for two months cause I can't find a gear anywhere!!
If the prop was spinning freely, it must have back-fired and loosened your prop nut. Apparently these kick-backs are hard on the cam gear?
You are lucky you didn't break a groove off your crankshaft, like I did.
My engine was running fine. I must have broke it some other time.
