Strange Weber Idling Pattern
Frodaddy
Posted on: 2005/9/15 1:25
I am in the process of trying to get another old Weber 32/36 running on the A12 and have come across an interesting symptom I cannot solve. When idling the car idles anywhere from 500-1500 then 1000-2000 then 200-1200 in a repetitive circuit style fashion. What could be causing this and why will it not idle constant?
Thanks Brock

Primary throttle shaft. On the accelerator cable end, can you move it up and down?
This creates an airleak. Could also be a sticky float/needle and seat. Could be something else. . .

Pretty sure the shaft had no play when I put it on. Will check again though. After doing some reading it might be the Idle Air Correctors which i did not know about.

it's probably not the idle air correctors, if it were those it wouldn't vary.
First use a can of carb cleaner and spray around the outside of the carb and see if the idle changes, that will tell you if you have a vacuum leak ( most likley )
