This is WEBER part Number 18990.061 and does not feature a cold start/choke device. We can supply these carburettors with cold start/choke mechanism - Just ask if you want them. Generally speaking the choke is hardly ever used on these carburettors even for cold start mornings.
By pumping the throttle with your foot on the accelerator pedal about 5-7 times is adequate to get the engine started. Accelerator pedal is used for a few minutes until the engine is warm enough to idle by itself. If you do not wish to adopt this'old school' starting procedure, and would like your carbs to feature cold start/choke mechanisms - just ask!
