Good luck with your cl. If you read my whole thread, which can get boring at times , the other members have given some great info on advance, and carb tuning.

This article is from last year but I just came across it. Pretty good read about a '71 Cl100.

So I realized that my issue with the cam chain tensioner was that the po, or whoever had this thing opened up before him put the wrong circle clip in, and from what I could see forgot the two 6mm washers that were needed on the adjusting screw. I drained the oil, opened her up and replaced the missing parts. I then reset the tension on the cam chain, rechecked static timing, replaced the old screws with Allen head stainless bolts, and refilled the oil. I went to fire it up, and it feels like it has very low compression, or like the motor is flooded. I couldn't get it to start. The spark plug was a little wet with oil when I pulled it. Before today, even with the loose chain the bike always started. Any thoughts on where I should start? I'm going to try to find a compression tester to make sure something didn't go wrong with the piston. I didn't mess with any internals except the cam chain tensioner.

Re-check cam timing, I think it's possible for chain to 'drop' and move a tooth when tensioner is removed

I did check cam timing. I had the cam cover off so I could check it before fully buttoning everything up and trying to start it. Thanks for the response. I think I might have a grounding or pinched wire issue from removing the stator. I'm going to retrace my steps this weekend and check all the connections and wires. If it's not that I'm not sure what step to take next.

Remove sprocket cover and check stator wires. The points wire is normally pretty 'safe'

As per Crazy's suggestions, I took the stator cover off and checked all the wires. The neutral switch wire was pinched but operational, everything else looked good. So I went back and re static timed the little cl motor. After resting my points to where they want to be now that the cam chain is the proper tightness, the bike started. I had static timed it last week and am not sure why it was so off, but happy to have it start. I plan to strobe it this weekend and fully set the timing. I'm very thankful for this forum and it's members for the great information and help.

You may have had points wire shorting out as there isn't a lot of clearance under cover.
It's pretty easy to do, ask any CB360 owner  ;)

I hadn't worked on the little 100 for a while. I have a couple updates. I ordered a set of Hagon shocks from Dave Quinn, and installed them. I checked the timing with a strobe and it checked out proper. Discovered the PO didn't wire the key and kill switch properly, so I figured that out. I just have a little carb tweaking to do, but otherwise it seems good to go for the summer.
