Well, I have brand new Edelbrock 4 barrel carb. #1813S 4077. It is a copy of the Carter AVS. It's the weekend, so I can't call Edelbrock.

Anyway, the driver side mixture screw offers zero change to the engine idle when I adjust it. I even took it all the way out, and nothing happened. The passenger side mixture makes changes when I adjust it, and the engine idles and runs terrific. The throttle blades are definitely in the correct relation to the transfer slots. I poked a needle in the hole with the mixture screw out and it didn't feel plugged. The metering rod looks fine too.

Even though it runs great, I'm curious as to why I can't get any adjustment out of it.

That side of the idle circuit is probably clogged up....

get a can of brake kleen or something similar with the thin red straw & give that port a healthy blast & see if that cleans things up

Do you think I should blow some compressed air through the mixture screw hole?

Thanks. I'll give that one a go as soon as I can go buy a can. The cabinets are bare.

holler how it turns out & if no go we will continue on for a solution

OK, I will type out... "HELLLLLLLLLLP"!!!! if I need ya!

Alright sounds like a plan & FYI go easy on the CAPS as there is a young man in Grand Prairie Texas who keeps us in line! Me I like em as my eyesight is fading but I gotta go with the flow

CTRL + or CTRL - will zoom in and out for you.

No problem. I will lay off the caps, but instead I will press very hard on the keys. I guess I can omit the exclamation points too, so I keep under the Texas radar system.

Noted! EDIT By God that works perfect

i'm so glad that my problem turned out to be a way to fix rapid robert's visual problem. i hate to think how long he was dealing wit it. ya see... i didn't use any caps! (oops. i used an exclamation point.) DANG IT!!!!!!

How is the carburetor doing?

Crap! I fell asleep. No progress will happen until I buy some brake kleen tomorrow. Unless my neighbor has some in his garage, in which case, I have to wait for him to fall asleep so I can steal it. Hah!

Robert, Should I steal... er-uh, buy carburetor cleaner instead of brake kleen???

any type of spray cleaner with the thin red straw will work to get up into that port. BK or starting fluid, anything along those lines

OK, cool. By this time tomorrow, my idle circuit will be fresh and clean at the very least.
If that doesn't solve the problem, I'll call Edelbrock on Monday. I'm sure they are just sitting around doing nothing.

calling them is not gonna take the carb apart and clean it.....

Thanks for that observation. Actually, the phone call comes after the cleaning. It shouldn't be filthy inside since everything is brand new with under 100 miles on a newly rebuilt engine that is running great so far. New carb, new gas tank, new fuel lines, new fuel pump, and a new fuel filter. Not to say that some debris didn't get in the system during assembly, but we're not talking about a car that sat around without running for several years. It doesn't hurt to ask for their opinion, because they may have seen this problem before.

What I really wanted to say to Hemi Rick is... "I can't believe you logged in to Moparts to say that unnecessary comment to me." "Please forgave me, but I thought Moparts was for promoting friendship and unity among Mopar enthusiasts, sharing knowledge, and having some fun!" "Some of us are trying to help each other get more Mopars back on the road." "I'm sorry if maybe your dog took a dump inside one of your shoes and caused you to have a negative attitude, but I don't think that your kind of commentary in this case, which you are trying to make me look stupid, has any place in Moparts." "Several members use this type of behavior, and cause fights." "It's very saddening to read things like that." "If you can't say something friendly and helpful to others, then please don't say anything at all."

"Thank you to everyone else for your help and friendship!" ...and to anyone who has pets, remember to check your shoes before logging on!"
