The manual says the marks should be facing each other. Which is what I expected to see when I took the cover off, with the #1 cylinder up, and the rotor in the distributor facing #1 terminal. But it is opposite of that. So I am not sure if I should put it back together like it was, or turn the cam gear so that the marks face each other like it says to do in the book. I don't know if I'm missing something here, or someone worked on it before, and got the marks off. You wouldn't think it would run if that was the case, but it ran fine, really. Starts right up every time. Just a problem with #1 cylinder compression, which I suspect is a burnt valve. I have a gasket set ordered for that, but it won't be here until next week. Until then I am doing the timing chain, which was real sloppy. No broken teeth on the nylon gear though, so I've seen worse.
