Hi all.
I was riding my Vespa px 200 the other day, everthing worked fine. Stoped for buying groceries, but when i tried to start it, it just wouldn't start. Not even bump start worked.
It got spark, and fuel getting to the carb. it's feels just like the key isn't in the ignition.
The flywheel magnets are good. The strator looks like it have no loose wiring
Anyone out here knows what the problem is ?

Best regards

New spark plug. Check if it has oil in the gearbox, to prove the clutch seal. Then if still no luck, I would try a different CDI box. These sometimes have spark but don't start.

I forgot to mention that I put in a new spark plug when I got home from my 1 mile vespa walk.

It's either fuel or ignition.

If it's getting a spark, the ignition is probably fine. Best way to test that is with the plug in the cap, and kicking it over. If the spark is blueish, it's ok.

So probably the fuel. Could be some debris in the fuel line, jets, etc.

Is the plug wet after trying to start it?
