I'll read up on that, thanks.But there are better threads which deal with the subject. Don't get panicked, read up, take your time, work methodically. If you turn the engine do it carefully and slowly. Once you are sure the cam/valve timing is correct, you can then turn attention to other problems such as carbs that might have made the bike run erratically.
Clutch cable looked good to me when I checked it out before, but I'll give it a closer look today. Yers, it's still the stock TCI but the battery is charging properly.Rust in a clutch cable can do the "no compression" thing.
Is the battery charging? If on the stock TCI ignition they will act exactly like what you describe if the charging system isn't working.
