Fit the Advance Idle vacuum capsule back to the carbys body. Don't forget the new seal. The middle hole in the photo.
Refit the choke assembly, put a smear of grease on it's pivot.
Refit choke clamp
Refit the accelerator pump jet, with it's new seal, all these seals easily role on.
I haven't put the valve that does nothing back onto my carby.
Finally fit the top of the carby back on, you will have to gently wind it on around the choke 'rod'. Once the top is back on in place, pinch the six screws back down, and put the new split pin back into the choke flap lever to hold it on.
