Joe, you're brilliant! The only heat I have is a hair dryer, but with some finagling, I was able to pry the cam off. How do you clean the inside of a cam? For that matter, what would you use to clean the zigzagger - I've not done any serious cleaning, and I'm not mechanically minded at all. Also, the lever that advances the gear only goes to the first sprocket, and the gear does not budge... The picture shows it as far as it gets (probably less than half way). Do you think more heat and oil will do it? (I can't find my oil, so I have to go out and buy some more). Thanks!
