Reply To: British Seagull 40 Plus Won’t Shut Off

[Monte NZ]

I have two Seagulls, both with Villiers Carbys and assuming you have the  same setup, the first thing I would check for, is to  look through the choke opening to  the throat of the carb behind, and see if the piston, (which is attached to the throttle cable), is going right to the bottom of the throat when you move the throttle lever backwards and forwards. You you should see the piston rising and falling and  if it’s not falling flush with the bottom of the throat the motor will still keep running.

The other thing to check, is that the knurled thumb screw on top of the carb has been screwed down correctly. You will see a little cut away in the top of  the knurled thumb screw  that allows the throttle cable to sit correctly…………it’s very easy to screw that down and trap the little cable fitting.

Hope this helps.
