Hey guys,
To start off I consider myself pretty knowledgable about SOHC Hondas and in the past year have had atleast a dozen of them, all of which were bought not running or running poorly. So this is nothing new to me. I picked up a 74 750 the other day that I was told wasn't running very good anymore. It came with a box full of ignition stuff, so you could tell someone was chasing an ignition problem on it at one point. Popped the bowls off and found all the main jets loose, and even one that had fallen off and was sitting in the bowl. Popped off the ignition cover and found a new points unit under there. Took it off and checked that the advance to make sure it wasn't stuck, put it back together and static timed/gapped it. The bike fires up and idles and when I put a light on it the 2/3 is working perfect but the 1/4 seems pretty jumpy and the timing doesn't advance right. At idle it stays at F for the most part, but as you start giving it throttle it varies from jumping back to T and to advancing a couple degrees. I've never seen anything like this before on one of my bikes. I've tried another new coil and it doesn't affect anything. Any ideas? The only thing I can think of so far is that the blue wire from the coil is shorting on something and causing the weird spark, which I am about to test now.
Thanks in advance
