Rubber /alloy starting choke solenoid tip for Vire 12 (Bing)

this part was never designed for modern unleaded fuel, or salt air, so will in time (10 years?) slowly perish.

when it perishes, the choke will leak and so the fuel will be too rich, or you will have to tune the idle mix screw less than 0.5 turns out (clear indication that it is leaking or float punctured). if your engine dies when you screw idle mix adjuster in less than 0.5 then this probably ok and not leaking.

easy to change or inspect, 17mm spanner to loosen solenoid, then withdraw collar against spring and swap or make sure you can see a perfectly round indentation in the black rubber tip, without splits or uneveness.

this part prevents fuel leaking out of the starting choke unless pulled back by the solenoid

NEW for the Bing carburettor on a vire 12 

The actual whole solenoid is no longer made, but i have ones refurbished on request exchange.

'manual choke' adapter is available now. Ive had made especially

there are basically only 3 problems ever go wrong with the V12 carb ; the float fails, the pump diagram rubber perishes, the choke solenoid tip perishes.(see other items). you cannot make any of those parts and will stop the engine performing/running, so carry spares.
