I have a 83 FB but my engine is out of my 80 SA

I thought my alternator was not working but it turns out it was the harness causing my issue.. (was running the harness from the SA)

Now that I have the FB wiring back in the car my stock gauges are up and running and my charging system is working correctly but I have a new problem due to my own ignorance..

Two "things" on my carb don't hook up to the FB harness so I need help to know what they are? Do I need them? and if so how do I hook them up?

 

Hmm well seems no one knows the answer?

I did at least find out what each one is called, but I still cant find out what I need to know in order to hook them back up (if needed at all?)

Top one (single wire) is called: coasting richer solenoid

Bottom one (dual wire) is called: power valve solenoid

They sound important to me..

 

Did you you download the 80 SA and 83 FB wiring diagrams and trace each circuit out? This woiuld really give you a good idea of how things are supposed to be hooked up. Plus it would be a good learning experience.

 

I started with the wiring schematics and can't either find these two items or cant make sense of what I am looking at in order to find the answer myself. Hence coming here to ask a simple question to those who would be helpful enough to give me a knowledgeable answer.

So am I to assume you also do not know the answer..

The very point of having a forum to me; Is the ability to have direct access to information. pooling of information and resources. etc.. And whereas is if you don't understand something people are willing to freely offer their advice, help and guidance.

 

Is that the 80 or 83 carb?

 

I swapped the engine from the 80 with carb and all. Its a street port engine running on premix.

 

you dont need them....they are for emissions. is the car running ok? looks like you removed the rat's nest on your picture. what is the carb/car doing?

 

yes the rats nest was deleted 2 po's ago when the engine was rebuilt and ported..

Seems to me that I have a slight hesitation/stumble in lower rpm levels than I had when they were hooked up.. It could be thou I need to adjust the timing.

Dose it matter if I leave them in place or should they be removed and plugged off?

If I keep them and hook them back up, I am pretty sure the top one "coasting richer solenoid" just gets plugged into a 12v keyed on source (although cant seem to verify this 100%)

The lower one "power valve solenoid" I think has something to do with the secondaries but cant fig out what sort of power source to feed it on each wire. I have read lots on "mechanical secondaries mod" but don't really feel comfortable tackling that myself nor do I understand why its done and how it makes improvement over stock vacuum set up.

 

it could be timing...maybe

i would start with the carb. clean the accelerator pump nozzle. the holes get dirty and the screw does also

then adjust the air mixture screw.

please let me know, how it works out

 

The harness for the rats nest is the one that has the connectors that your missing. It plugs into the passengers side of the firewall.
