- My 1977 Camaro (305, 2bbl carb, automatic) has always had problems stalling
- if I make a sudden stop or if I stop going down a steep hill. It has done
- this to varying degrees on and off ever since the car was new.
-
- The only thing that makes sense would be the carb float adjustment is off but
- I have rebuilt the carb several times over the past 15 years, and each time
- the float has been right on. I even installed a new carb about 2 years ago
- and it still has the problem at times. I had the new carb apart about 4 months
- ago and it's float adjustment is set according to specs.
-
- This problem seems to come and go to varying degrees. For the past few
- weeks it has been worse. I want to dig into it first chance it get but I
- am somewhat at a loss as to what to check. I have checked just about
- everything else. It had a complete tune up - new plugs, wires, air filter,
- etc.etc etc about 4 months ago and is running GREAT otherwise. Getting
- terrific gas mileage. It has lots of power/pickup, etc.. It sometimes
- hesitates a little when it is cold but once it warms up 5 minutes it is fine.
-
- But, I will be driving along, running great, then I stop at a light and it
- suddenly idles real rough. At the next light it may be just fine... If
- I stop suddenly it will stall 9 out of 10 times. After a stall I have no
- problem restarting it.
-
- This is driving me nuts!!!! Any ideas?
