Weber 32/36 choke

Postby bylzebub » Thu Apr 07, 2016 4:00 pm

I'm looking for info on the idle sequence for the electric choked 32/36 DGEV I just installed. My first choke heating element was a bad one confirmed with multi-meter so they sent me a new one right away. I installed this one and it clearly got hot and opened up the choke plates but that didn't take the truck off high idle. . .

This is what I would assume would happen:
1. Tap throttle - choke shuts - truck starts - goes into high idle
2. The spring heats up and slowly opens the choke plates in roughly 3 min depending on temp.
3. After choke warms up the truck kicks off of High Idle to normal idle without touching the throttle.

Mine has never gone off high idle on its own but as soon as I touch the throttle it kicks down to about 900 rpm, even if its cold.

So is that how its supposed to work or do I have something set up wrong?

BTW this weber carb is the s***. Anyone that owns a 720 and is still running the stock carb is doing it wrong. I was ready to sell the truck before I finally decided to run a new carb on it. If you're on the fence just do it already, you'll never look back.
