So I never have been able to get the electronic choke to work right on this. When I first got it I noticed that it had a crack in the housing. What I've had to do is just manually rotate it so that the choke stays wide open all the time, otherwise it sputters and dies.
When I was messing around with it hooked up and the engine running, I wiggled the wire a bit while it was connected and the idle would change by a couple hundred rpm, like it was doing something. I have a feeling though that middle bit shouldn't just spin totally free like that, and that something rattling around inside probably isn't good either.
Also forgive the angle, shooting in the sunlight with the pad while trying to see something in your hands isn't the easiest thing =D
