Quick question for those with much more knowledge than me....
We're talking about my '72 Newport with the 400 and original 2210 carb. So, I've done a bunch over the last few months and have most things sorted out to make this a fun summer car and it has gone well. It has been running like a top so I took it to Mount Desert Island here in Maine last Sunday (about 200 miles round trip) and it drove beautifully. Parked it and fired it up two days later, no problems initially but got to the first stop sign and the second I stopped, I noticed that it was idling really low..... on the brink of stalling or like it has a fire-breathing, high HP cam in it. I put it into neutral, same thing. Put it into park, same thing. Once I got going, it was smooth as can be.
Well, I started reading threads on here and found a few pieces on info to help me diagnose (smelling oil for fuel, wrong order from the distributer) but all of that checked out. I thought maybe due to the long drive, the idle screws may have loosened b/c honestly, I thought it just needed to be idled up. Interestingly enough, with this problem, fast idle is now what a warmed up idle should be and my curb idle is super low as I previously described.
So, I pulled off the air cleaner and checked the three vacuum hoses that come off of it and all was well. I looked things over, found the idle screws and fired the car up. I noticed it seemed to be running better. I let it warm up and moved it around in my driveway without the air cleaner to get it to click down to the super low idle I'd been experiencing and I couldn't get it to do it. I still idled it up a half turn on both the curb idle and fast idle and it sounded great. I decided to throw the air cleaner back on and the second I put the vacuum hose on the back of the carb that goes from the throttle body to the sensor looking thing in the air cleaner (technical name for it, I'm sure) it immediately bogged down. Vacuum line is clear and in good condition.
I've pinpointed the location of the problem but in researching what it is that is in the air cleaner and what I need to do to it, I've come up empty. I'm guessing there are more than a few on here that know exactly what is going on. I wanted to just leave it undone and drive but thought I check with everyone here first. Thank you in advance for any info you can provide!
