.. when the scooter is runing :wtf:
Also only seems to run with choke out. Checked the spark plug is tight which it is. Does that mean possible a loose head or a snapped ring?
Air pressure coming from the spark plug hole...

my monies on a loose head/ blown gasket.
Scootering since 1968.
Its with the metal protective cyclinder cowl on that there is a disticnt pressure of air blowing out from the hole where the spark plug goes in. Then as soon as I push the choke in, the engine dies.eden wrote:When you say the hole do you mean the hole on the cowl or are checking with the cowl off?
air obviously gets blown out of the cowl by the flywheel when its running.

That's because it's an aircooled engine and the fan blows air across the cylinder fins ,some of which escapes from the spark plug hole in the cowling. Which is unusual to be metal on a px200 
If it only runs with the choke it sounds like you've got a blocked up pilot jet or carb passage , or either main seal has gone .
