I have a question regarding the electric choke operation on a weber carb.
Can the element go bad or as long as the element is not broken, and the hook up point if fine, it's good to go?

Older chokes are better than new ones. A visual check is good while looking at the unit. Check for loose rivets on the new Empi shit. They are a problem.
Set (turn) choke element until the two butterflies begin to close. Once they close revolve about 1/8' FURTHER. Leave air filter off while starting engine.
Butterflies should open after 5-8 seconds. If not ---reset. Judging by your avatar; you're talking about a Weber Progressive.

Yes, a weber 32/36 with electric choke. Temp here is 19F. I timed the choke and it was almost 10 minutes to fully open. Weber said it should be fully open after 3 minutes. But does the temp outside determine how long you should set the choke for?
Colder temp = set choke for longer
Warmer temp = set choke for shorter

I like to see the choke fully open in 3 to 5 minutes at any ambient temperature. It is sometimes necessary with the progressive to set the choke leaner for winter use than for summer use, so a semi annual adjustment may be called for. |
