  • If you can get the air cleaner off I'd like to see a picture of your carburetor from the driver side. I want to see if you have the anti-stall dashpot. That is there to keep the car from stalling out when the gas pedal is released.

    • Thanks for suggestions. I will take a photo later on tonight. I can get the air cleaner off. That seems easy enough!

      And yes the engine never stalled in neutral. It felt a little rough at lights. Setting the idle may fix everything. =)

      • Going through paperwork that came with the car. PO looks to have replaced tuel line 9 years ago. So that's something at least. Part came from Thunderbird HQ, and when the car was lifted I was told the lines looked good and were newer.

        • Car Broke Down First Drive

          Regarding that OIL light coming on again, as has been mentioned before.. Why would it come on? It would IF you were low on OIL! have you pulled the dipstick and checked the oil level again? As I recall, you did that in the past but it was full. But there has to be a reason why it is coming on, IF it is NOT low on oil... Perhaps the oil sending unit on the block is bad. Or the wiring from it is bad, intermittent, not getting enough of a signal to the oil light... Perhaps others will comment on this, as I am not a mechanic.. Just a Lover!

          • This is what I am not sure about - how to tell. The OIL light goes out when I am moving and applying the gas pedal or coasting. It when I come to a stop in drive that the light comes on and feels like it wants to stall.

            I wouldn't mind setting the idle if I could get instructions on how to do this.

            • I guess I don't really know the answer to this. Tried to hook up with the club's mechanic but couldn't catch him home. I will reschedule.

              • If the idle speed is too low or the car is about to stall out the engine is not rotating fast enough to generate enough oil pressure to turn the light out. Nothing more complicated than that.

                  Kirsten,

                  Remove the air cleaner. The driver side of the carburetor should look like the picture. The idle speed screw is shown in the center with the spring underneath it. Turning it clockwise will increase the idle speed. Make a mark on the screw and somewhere on the carburetor body with a Sharpie so you know where you started from. Make small adjustments (1/8 turn at a time). You can do this with the engine not running. After making the adjustment test drive the car. If it feels like the car goes into gear too hard when you move the shift lever then it's idling too fast and you want to turn it counter clockwise a hair. If you come to a stop and take your foot off the brake and the car wants to creep excessively then it is also idling too fast. I don't think you will have either problem as it appears that your idle speed is too low. I imagine you won't know if it has done any good until you have the car good and warmed up. If it still feels like it's going to stall then turn the screw another 1/8 turn. Hope this helps.

                  • Thank you John! Awesome advice. I will do this.

                    • Update:

                      Drove a couple hrs today and nothing bad happened! I did two things differently.

                      1. Made an adjustment to the carburator as suggested (1/8 turn clockwise)

                      2. Drove the car in D2 setting the entire time.

                      I never had to shift into neutral to prevent a stall out. That's the good news. Would welcome feedback.

                      • Driving in D2 would make no difference as it idles the same in both positions. I would recommend driving in D1 as the pickup is much better. I would say the carburetor adjustment or the cooler temperatures are more responsible for the car not stalling.

                        • Good to know! That makes a ton of sense.
