Starter circuit Keihin 50

[mclark999]

For testing the auto choke/bystarter, the manual says to try to blow through the circuit when it's cold. The hand drawn picture in the manual shows them blowing through a hole at middle top. From actual picture you can see there is no hole at the top. Any ideas?

Although it would require initiative on your part . . look for an exterior casting bump (internal passageway) from the enricher base to carb inlet.

Btw, when I blow into the three different tubes when the scooter is cold, they are all open. On the right and left, I just heat air blowing through, but the bottom, middle one I hear gas bubbling and if I suck on it gas comes out.

Thanks. That was easy. It's the hole on the right. Passage goes right to the enricher.

This procedure passes, but when I connect a volt meter to the yellow and green wire when the scooter is running, it's only reading half a volt, not twelve volts.

Ok, so the enricher is working right. It shuts off the passage when it gets hot as it's supposed to.
