Figured out that the kill switch wire to my cdi wire was grounded somewhere and therefore not giving my coil any voltage. I cut the wire and it worked. Now I'm trying to decide whether to run a new wire just to a toggle switch or figure out where the issue actually is and fix it.

So what jumper wires do I need to run to my CDI to trick it into working right? I feel like this is the problem just based on the fact the I have voltage going in and none coming out.

I have 50cc scooter that I am failing to get any spark on. The wiring on the thing is a little bit of a mess towards the front end (this is how I got it). Originally I thought the coil was bad so I tried a different one and that didn't do the trick. The next logical move was to try a different CDI box, tried 4 different ones with no success. Next thought was bad stator, so I broke out the multimeter and did some readings on the wires coming off of it. I should also add I have tried two brand new spark plugs.
I have a black wire which I believe to be my CDI power that is registering about 75 volts AC.
I have a blue wire which I believe is the Trigger Pickup wire that is registering around 1-6 volts AC.
On the black/green wire that goes to coil I am not registering any voltage (from what I can remember).
According to the information I have found about stators these readings are in line with a normal functioning stator.
One thing I am curious about is if I am having a problem at my ignition or kill switch. Is there a way to trick the CDI into thinking that it is on?
One more thing. I think this moped was equipped with an alarm and remote start. Both of these things seem pointless to me. Can I safely remove them without any problems?
Any suggestions about what to do to get some spark would be great.
Thanks

I'm going to set the valves tomorrow. There is plenty of spark and It will press my finger off the hole when I try to start it. Only thing I'm not sure about is how much it should blow my finger (obviously it would be ideal if I had a gauge to check it but I don't)

My scooter recently quit running right. It used to bog down after it would seem to get hot or after it had bounced around a lot ( not sure which) and then would bog down almost to barely moving. Then one day it just pretty much quit starting. So, I bought a new carb and slapped that on, slapped a new air filter on, put a new spark plug in, put a pcv valve on, and put a new fuel filter in. It still won't start. It seems to be on the verge of starting when you turn it over but it never really goes. I've made sure I've got spark. I 've got compression. I sucked on the vacuum line that goes to the petcock and it squirts out fuel when I do. The carb is full of fuel. I tried spraying starting fluid in through the carb and still nothing has changed. I've also tried placing my hand over the carb and tried to start it. Nothing. Any suggestions to what it could be? I am possibly gonna try a different CDI box this weekend. I'm really at a loss on this one.
