32/36 DFEV choke operation question

Post by nelsonj »

Hi all. I had my mechanic put in a Weber 32/36 DFEV carb about a year ago. Love the carb when driving, but ever since initial installation I have been concerned often the car is hard to start. Anyway, I currently have the air cleaner housing off the carb so I decide to try and see if the electric choke is working properly.

Good news is I have 12V to the electric choke with the ignition key in and turned one click from "starting" (power comes from the original idol solenoid valve from the stock carb I believe). Bad news is the the choke valves do seem to react when they get power. They just stay in the "down"/vertical position. I expected them to "flip up" to a horizontal position during startup, but they don't seem to move.

Here goes the questions:
1) Do I have to do anything to activate the choke (like press the gas all the way down, or depress the clutch went staring)?
2) Assume a cold start - what does the proper operation of the choke look like? Should it "flip up" horizontal as soon as I put turn the ignition key? Should it stay lockup up horizontal as soon as I depress the gas to the floor?
3) If I have 12v power to the choke, but it is not moving (flipping horizontal when staring), what else could be wrong? Could I have a defective electronic choke?

Anyway, I am sure there are experts out there that understand this choke. It sure seems to me that, even though I have voltage to it, mine is not working properly.

Thanks in advance for any help/ideas.
