Found an online service manual!

So I recharged the battery that I bought over the summer, and received the same results. Only 1 spark plug would ignite, I believe this is a problem with the ignition coil, what the coil does is convert the low voltage from the battery to a more powerful voltage which is needed to ignite the fuel mixture within the cylinder.I faintly remember my father telling me that he has a coil that would fit this model bike, although he is out of down and I am unable to find it myself. Knowing that I am not able to solve the coil issue myself, I moved on. After searching online for a while, I found an online service manual for this model bike. Although this manual is free to read online, if I wanted to download the PDF for printing it would cost 5 dollars.A Hard copy of a service manual is vital for engine work because no one wants to get their computer all greasy when they are reading. I plan on purchasing the manual and printing it in the school library (all 300 pages) if the librarian permits. When I was thumbing through the free online manual, I stumbled across the engine timing section. I learned that the timing must be re-adjusted whenever a ignition problem has affected 1 cylinder and not the other, (ex. the coil preventing one cylinder and not the other). I began by removing the contact breaker cover, and the  alternator cover. This revealed the points, and crankshaft. I used a 14mm open end wrench to turn the crankshaft manually which caused the points to rotate and demonstrated how ignition timing worked. I did not proceed because I did not have a hard copy of the manual, and there was no sense in timing an engine that did not have a functional coil. My next step is to get the replacement coil from my father, install it, and then attempt to time the ignition.
