I recently bought a 1981 CX500 for super cheap and the guy I bought it off of told me it had a bad pulser coil but that it wasn't a big deal. I got it home and did some diagnosing to figure out what all was bad and found that I had no spark to my left cylinder and a weak spark to the right. Naturally, I went to see if it was the ignition coils and found that the wires coming from the CDI were both reading 2.5 volts. I continued to research and found that my issue could lay in the stator so I did resistance checks using a very handy picture I found off this forum, I concluded that 3/5 and 4/5 were both giving no readings however the rest of the leads were in the normal range. I was told that my stator and LH adv coil were bad so I went ahead and ordered the stator (the engine is coming out to be painted anyways and the stator was cheap so it wasn't a big deal). I am now stuck with this, what am I to do about the LH adv coil? I was unable to find any for sale to replace so is there any way that I can repair it? it is my understanding that it is not "required" to run but there will be a loss of power due to incomplete combustion and poor timing, is this true?
