Cg125 wont run
« on: Aug 18, 2017, 14:02:18 »
Hi guys.

So here is my situation. My cg125 was running perfectly. The other day I lost the spark. Turns out the points adjustment screw had come loose. I had to pull the flywheel to reassemble the points. I have refitted the flywheel the same way it cam off. I have reset the points as per the manual. I now have a spark.

Heres the problem. The bike is hard to start. Sometimes kicks back. When it does start it wont rev above idle. Opening the throttle causes a stall with a loud pop and grey smoke from the carb. The plug is very black.

I havnt made any changes to the carb and it was perfect before this problem. Have I made a mess of the timing? Would the ignition cause problems like this or should I be looking at the carb?

installed the points place 180 degrees away from where it should be.

there cold also be a short in the capacitor wires.  make sure all the insulators are in place and the wires are not touching anything. Not your ordinary Blog site.

Had another look this morning with a clearer head. I had gapped the points wrong causing the ignition to be retarded too much. All fixed now thanks
