Low/Rough Idle Question

I hope you find your solution. It is out there. Much useful information above, and it is great you are sharing what you try as you work through this dieseling. In my own, limited experience, the '90's era Weber 32/36s that I rebuilt, responded well and I am very happy at how they perform now. But I would not proceed with any rebuild if I could not deal with throttle shaft vacuum leak. Fortunate to have the Canadian distributor for Weber here in Vancouver, and I installed these inexpensive bearings that eliminate the vacuum leak in older Webers. Yes, may not be your issue, and only part of the process, but these helped me get to the end of the quest for tuned, synchronized, strong idling and no dieseling, pair of Webers. Good luck and keep us updated! Mike

@bluecoupe30! - can you share the link to that site please?
I'm close to Seattle so shipping from that Vancouver distro would be cheap if I find I need those parts. Thanks.
 
Me again...so going to do a full ignition timing sequence this weekend since an additional 1/8 clockwise turn of the dizyy did not correct the dieseling at shutdown.

Sorry for the noob question but how/where do you adjust the idle so you can get the RPMs to increase to 1700?

I know where the idle speed adjustment screws are for each carb, but since they are synced and share a throttle linkage, do you use the one for the front carb, the rear carb or by other means?

It has been a while since I fiddled with a dual carb set up. I believe that if you study the linkage you will find a set screw for your purposes.
