First off I know I've been asking a lot of questions about this carburetor and putting it back together, but it's a first for me and I just want to get it running again!

I eventually got the carb put back together correctly, all the linkage hooked back up, vacuum lines, etc. I cranked it and it fired right away just like it always does. I did NOT have my MCS hooked up as I was trying to see if the carb was getting fuel (before this attempt it was not). The motor was running extremely rich, didn't even want to rev because of all of the fuel I assume.

After running for a minute or two, I was satisfied and shut it off in order to button up all of the rest of the parts back on to the engine. When I attempted to start it again, I got nothing. It just cranks. I removed the carb again to inspect it, making sure it wasn't clogged and to ensure that it was getting fuel, and it appears to be fine. When I manually work the linkage I can physically see fuel entering the carb.

Prior to rebuilding the carb, I did a full tune-up. I replaced the dist. cap, rotor, spark plugs, plug wires, fuel filter, set the timing to 10 BTDC, etc.

What could have happened? Is it possible that I fouled the plugs with the motor running as rich as it was? What else could I check? I'm at my wits end here and I need to get the Camaro running again so my wife and baby can run around in our Trailblazer while I'm at work. I appreciate anybody that could try to lend me a hand and figure this out!


I asked this question in the V6 forum so I do apologize for reposting here, but this was likely the better forum for my problem anyway.

 

that would be my guess is it fouled the plugs. you can rmove them and try to clean them but a new set is cheap.

 

Thanks for the quick reply, I'm about to head outside again to check the plugs. This carburetor has been giving me fits but I suppose in the end it's a learning experience. I could put the linkage back together with my eyes closed now.

 

I pulled the number 1 plug and it's as black as black can be, but it wiped clean. I'm going to try to clean them up, as they're brand new, and as soon as the new MCS gets here via eBay, we'll give it another shot.

Thanks!

 

I have having the exact same problem i rebuilt my carb and now the engine wont start my plugs were black as the night and smelled like straight gas. I dont wana replace all the plugs but let me know wat happins soon as possible thanks.

 

Alright, latest update:

Received my new mixture control solenoid in the mail. It's a brand new unit, albeit probably 15-20 years old, in the original Borg Warner box. lol Installed it and cleaned up all of the spark plugs with carb cleaner, they look good as new.

2 pumps of the gas pedal, depressed the clutch, turned the ignition and it fired right up as if it never had a problem. Ran it for a few minutes to ensure it was running smoothly after it reached operating temperature, fitted the air cleaner back on and took it for a test drive.

She's peppy again! It's been nearly a month since I've driven it, but I do feel that the car seems more responsive than it was before, the carb rebuild may have something to do with that.

I'm STILL getting a trouble code "54", which is for the mixture control solenoid though. Is it possible that the code was stored from before? I've got the battery disconnected right now to reset the ECM. If it still reports the code, what could it be? The wiring itself? Does the wire run straight from the MCS to the ECM?

 

It was the module in the distributor cap got a new one and fired right up.
