I know it sounds a bit of a dopey question, but can someone tell me how the choke operating mecanisim works on the '08 Beta's?

There's a knurled screw that seats when wound in (clockwise) but can then be turned anti clockwise forever!

I could fiddle and work it out for myself, but it would be nice if a current owner would just be kind enough to tell me?

Thanks

pull up to choke push back down for off. no turning needed.

The knurled screw is a mixture screw, leave that alone. The choke is a black lift up piston on the wrong side of the carb hidden by the exhaust

Ah! that explains it.

Problem i've got now is i've been fiddling with the mixture screw whilst looking for the choke!

I don't suppose you know the setting for the mixture?

Thanks again

Screw it in to stop then back it out one whole turn, if nothing else has been altered ie jets and needle and reeds it should be a good starting point. I think there is more info on beta uk site.
