I have run into a big wall on the restore of my '72 CB175. Was wondering if someone could point me down a path(s) to getting some resolution. There's a lot of issues with it, but for now I'll focus on the main problem, no spark.
I finally got it running the other day. Was letting it sit and idle for a bit to run some Sea Foam through the engine. After about 15 minutes of idling steadily, it died suddenly. No sputter, no slow down then die. Just a sudden stop.
Pulled each plug out to check for a spark, neither plug has a spark.
At this point I thought I would check the breaker points. I adjusted the gap slightly, put some contact cleaner on the points, scrubbed them a bit with a point file. While I had the cover off, figured I would look at the static timing. Using a simple volt tester (like this http://cl.ly/3azi) I clipped the alligator clip to the breaker point (where the wire connects to it) and then touched the other end to the engine block. From what I understand, the light on the tester is supposed to light up right when the "F" mark on the rotor hits the index mark. But, my light stays on no matter where the rotor is turned. Never turns off no matter where the rotor is turned.
What's going on here? And, am I doing something wrong with the timing light?
