Auto Choke Operation

[bmetras]

Can the auto choke for these scooters be bench tested? And what should I expect to see. Received a new choke today.. without mounting in the carb. I plugged it into the harness in place of my old one which is installed in the carb. When I started the engine, I see no movement of the needle from the new choke.. I then unplugged it from the harness and hooked an external 12v source to it on the bench .. still no movement.. am I testing incorrectly or did I buy a dud.. thanks for any info..

Put it on your bench on a sheet of paper, hold it down with something heavy, mark the position of the plunger on the paper, apply power to it, wait 5 minutes, see if it has moved out.

Thanks, I thought it was supposed to retract under power and then extend when warm .. my mistake .. back to the bench ..

Thanks again ... just re-checked .. good 5mm of protrusion after it warmed up..

There is one terminology for an automatic choke. It is called SCI. That stands for Shit Can It & use a manual choke. That's just my $.02. but everyone likes something different-Different strokes for different folks! Sorry to belittle your thread. Irish

5mm is the expected travel.

You should check your wiring to verify both ground, and input voltage.
Some scoots run DC +12 volt, and others run AC +15-40 volt
