Should this be plugged or filtered or should I just leave it alone. After I shut my engine off I saw smoke rolling out of it.

 

plug it.

that was the vac leak on my carb causing it to not idle. took me a while to track it down.

 

unless I'm mistaken, that is supposed to be a solenoid, and you can take it out take it apart and gut it (if your careful) and put it back in, but without it you get nada. You seem to have some of it (or something ) stuck inside keeping it open.

 

Well mine idles fine and I bought the car recently so I'm not sure what may have been done to that particular hole. The car has no rats nest or any other emissions stuff. I'm tempted to just leave it alone cuz I don't wanna mess with it and then have my car not idle but I also don't want my engine sucking in dirt and debris threw this hole.

 

That's where the the richer solenoid goes, from what the original rat's nest removal tutorial states, and Sterling, you leave it in, unplugged from the wiring harness.
Your solenoid is missing.

 

Here's an active thread with a problem possibly concerning the richer solenoid.
From what I understand, the solenoid keeps the circuit closed until activated, so with out it there, you have a leak.

ok but my car runs fine and has plenty of power if i had a vacuum leak it wouldnt. right?

 

It is a vacuum leak, and it will effect idle. Whoever had the carb before had to have compensated for this giant vacuum leak at some point by adjusting the idle accordingly, so if you plug it, your idle will change. You can just hold your finger on (or close to) it while the engine is idling and see what I mean.
You can either plug it and re-adjust the idle (...which is what I suggest), or stuff a piece of gauze, filter paper, screen, whatever in there to filter the air. Eventually that will start to clog up and effect your idle, though.

 

thats where the air vent solenoid valve goes. its job is to vent the float bowles to the charcoal canister after you turn the engine off. get another avsv to install in there.

 

I have a couple extra carbs and verious parts anybody gotta pic of this part and how it's supposed to be all hooked up to the canister.

 

My advice is to follow Sterlings advice. I don't know of anyone that knows these carbs better.

 

To be honest I didn't even realize that was who posted that but I was planning on taking his advice anyways. I definitly appreciate and respect his sterlings opinion. I was actually just reading his page on how to tune a nikki yesterday.

Would still love to see pics of the part I'm missing and how it's supposed to be hooked up.

 

No, that's on the other side, up top.

The carb manuals are in PDF form on my links page. They're floating around all over this forum, too. There are exploded illustrations that show all the components.

 

go to www.sterlingmetalworks.com Theres a bunch of links that have will provide you with the info you seek. Good Luck

 

nobody has a pic of this part? neither of my extra carbs has one either.

 

here ya go..

:AA:

 

ok cool ive got a couple of those. not sure i have whatever it plugs into though. wouldnt happen to have a pic of that would ya?

 

does it need to be plugged in or can i just screw it in to the carb?

 

good call. for some reason i thought that i was looking at the left side of the carb! good catch!

 

ok i lied i dont have one of those. thought i did but nope. anybody got an extra? would plugging the hole work?

 

If you look at the picture of the richer circuit, that DivinDriver posted, in the link I posted, you would need something to push the plunger in to keep it from enriching the mix(richer solenoid). Plugging the hole would just eliminate the vacuum leak. You may be able to rig a plug that also holds the plunger in, if nobody has a solenoid for you.

 

did not think of that. i just plugged mine up. how necessary is it to keep the plunger in? i know i could rig something to keep it in. just wondering what the consequences are.

 

Done as you described the richer circuit will always be active, it will need an idle adjustment to compensate (or probably already has it done). Also makes a louder suction noise.

I'd just shoot some silicone instant gasket through the orifice and leave it overnight to cure. Then cover the hole with a cut-short bolt.

 

noted ill do that today or tomorrow.

doesnt sound like its harmful tho. ill just be running rich. gas mileage isnt that important...

thanks, Nick

 

K will have a richer solenoid on the way soon. It's plugged for now should I unplug it or leave it plugged till it gets here? Also when I get it put in should I plug the electical plug into something or not?
