Carby Still having issues after Naked Man Incident

[2xclutchin]

O.K. so as some may remember after the naked guy thought he was driving my car, it won't idle, or it will until the choke shuts off. (Which makes driving and braking in town a little dificult, having to restart at every stop sign almost)

I'm really out of ideas on what the heck the problem is. I can't figure it out. Is it getting to be weber swap time? I'm at a loss. It's for sure the fuel delivery in some way shape or form. I'm kinda looking to hear a list of things to look at from the carby guys on here. Adjusting the idle screw by the way, does absolutly nothing, and never has.

Thanks for any help..

Nothing in my troubleshooting guide about car being faux-jacked by naked guy. You say the plastic idle screw NEVER made a diff? Sounds like something is holding the throttle plate open. Check to see it the end of screw is contacting something. Also see if closing choke slightly allows it to idle (indicates fuel starvation).

(indicates fuel starvation).

This made me think of a problem I had, and may not be the issue you have ... but...
.... you never know and is an easy check

I had issues with a fuel line that was twisting and kinking under pressure from the fuel pump, cutting off fuel to the engine. (carb pump pulls and creates a sucking type pressure on the fuel lines)
The fuel line I am talking about is the short rubber line between the metal fuel line thats at the bottom of firewall, and the fuel filter. It is very short, and makes a sharp bend to reach the filter. With age, the fuel hoses become softer and can twist/collapse from the sucking pressure of the mech pump.
Check that and at least you can eliminate that as the problem.

Good luck!

Assume you've cleaned inside the carburettor with carburettor cleaner spray?

I had a choke return spring bust on one of my B2200's. Caused all kind of heck. If the NakedGuy was stomping the throttle repeatably, that is something that very well could have gone awry.

Screw is actually not in contact with anything.
When choke is closed all is good, once choke is off (open) it wont run without the foot-feet being depressed/feathered.

Line appears to be fine, but I need another human to run the car for me to look while pump is running, but also as long as the foot-feet is depressed it's fine, just at idle does it not want to run.

Carb has been cleaned, not taken off and cleaned but cleaned on the car. (Spraying carb clean whilst running.)

Maybe but the choke does shut off. That's when the problem happens.

Answered in order that comments were sent.

Seems like screw should be in contact with throttle plate at idle. I will check my '89 come daylight. Your carb might be rigged and might need to be removed and put to spec. My friend across the mountain has a brand-new unit for $150 with the plastic covers.

[georgeb]

I have a carb manual and pic shows screw against throttle lever. There are two electric switches in the idle circuit. One will not let it idle if it is not energized. It is called the slow cut fuel solenoid and is controlled by the ECM. If it's not something electrical, it's most likely dirt.

[drddan]

Try turning that screw in until it touches, and then screw it in until it raises the idle a bit. I believe it should be doing something, besides hanging hanging in the air. :p

[2xclutchin]

The screw is screwed all the way in now, and is not touching anything. Still won't run at idle upon the choke opening. Wish I knew more about the electronics of this conflabin thing. Also georgeb if I can't work this out I will be doing the weber swap, at least then you can trouble shoot without a college degree. lol

[georgeb]

Did you turn the plastic screw both directions to see if it makes contact with something? Don't know if that is the main problem but it indicates something is amiss in the throttle linkage.

[2xclutchin]

Neither way will it come in contact with anything. Maybe something got bent by the unclothed guy?

[2xclutchin]

Well, my throttle shaft is loose, causing a vacume leak. Where do I go from here? This also sucks because the NakedGuy won't have to pay a dime, when I had a working car prior to everything. Is the only way to fix the feedback to replace it now, or can one replace the shaft?

[georgeb]

Doubt if naked guy caused loose shaft. Don't think that bushing repair kit is available. I know where brand new unit is for $150. PM me.

[2xclutchin]

Didn't mean that he caused loose shaft. I meant that he mistreated the pedal, causing things to finally not even half arse work anymore.
