Can someone help me pls?

I'm in need of help, I have a peugeot speedfight 2 50cc LC 2001 and I cannot get spark, I've changed the following:

Stater
Cdi
Coilpack
Sparkplug
Whole new wiring loom

If someone has any ideas can you please put them below or something, much appreciated.

 

The starter motor works when I turn it on.

 

Is all the above new parts, or used?

 

Used but came off fully working peds

 

Check the connection to the cdi.

 

Yes, I have, I've tested all ports and gave them a little clean

 

Battery?

 

The battery is connected and gives out electric

 

How many volts?

 

Try a totally new spark plug, not a used one. Sometimes it's as simple as that

 

Ah, okay thank you, I'm off to get one tonight then, I'll respond and see if it helped or not, cheers

 

Start with the cheapest thing first.
Top tip from a mechanic there.

 

Also fun fact, if you use a 4 stroke Honda cdi, your Peugeot will start and run backwards...

 

Just changed spark plug, but still no spark. I have no absolute idea what Could it be

 

Inspected wires, no problem with those

 

Are you getting power to the cdi?

 

Yes, I've tested the wires there too... .

 

Check the air gap between the pickup and the flywheel, should be about 1mm.
Also make sure both surfaces are clean (the round pip on the pickup and the raised section on the flywheel)

As the raised piece of the flywheel passes over the pickup it sends a pulse along the wire to the cdi to tell it to send a signal to the coil which then creates the spark.
