Gen 2 weber swap. Anyone have an idea or three for why she wants to idle between 2500 and 3500 depending on how warm the car is? I have corked all the remaining vacuum ports and hoses as per example on my hatch. Throttle cable has slack. What else is there?

Does it run at that RPM all by itself? Engine RPM is controlled by air/fuel mix. Don't go by the throttle cable. Look down the throat of the carb (car not running) and make sure the plates are closed fully and it is not dumping fuel. Make sure the choke etc is all properly set up. If it is not flooding sounds like a binding issue.

Will have to check for fuel dumping. Choke is not connected to power so it is all carb. The adjuster screw with spring is not touching anything.. I havent removed the linkage to give it a little love yet so I thought I could leave it be for now.

"the adjuster screw thing" should be toucing the stop, that is the idle speed. The fact it isnt touching means that the throttle is stuck open for some reason. Something is binding.

If you used the Hitachi's cable plate, there can be binding between the peice on the end of the cable and the choke linkage. Check there.

Couple of flat washers installed on the throttleshaft before cable plate is easy fix. Done that on 3 Weber installs.

I believe I did add washers however I still need to move the cable bracket or fab one up it is currently too short and at the wrong angle but I have forcibly made sure the linkage is backed out all the way, so if there is binding I will have to find it elsewhere or just haven't seen it yet. I will check it out in a few.

 

 

3 hours later.. I did find one potential problem with my washer being too big so I swapped it around with a less broad one and now clears though I don't think it would have been major since it's only job was to keep the factory throttle thingy ( gotta love the technical terms ) from hitting the Weber linkage. Still not seeing the problem so I suppose the next step is too remove the carb and check for other things that may cause binding or possibly being stuck open/closed.

I hope the gaskets survive.

So I pulled the Weber today and played with it. I believe my problem was binding linkage. I may have over-thought the assembly and overtightened the nut because it had a little play... a mm or two. fixed that, just backed it out a little and and Bam! no more sticky feeling. Unfortunately I was messing with the butterfly first thinking it may be the culprit and be reversed 180 and stripped one of the holes pretty good and one of the screws is now a basket case. Any ideas on where to find parts or would it be better just to send it to someone and have it done?
