Topic: Need Help.Posted: 18-October-2016 at 6:07PM |

I'm new on this site. I just purchased a 1971 Torino Gt. It has a 351-2v about 2 weeks ago. In the last 2 days the car dies when going from a stopped position into a turn or when putting into park. It is an automatic so there's no way it's stalling as a manual would do. I believe it is running rich because I do smell gas. Can anyone confirm it is the carburetor or is there a place I can start to look for the problem. Any help is welcomed.

Welcome to the Family.
First thought is yes you have a carb problem. Good news is the Ford 2bbl is one of the easiest carbs to rebuild. the kits are about $20 at any local parts store and with a can of carb cleaner, some small wire or tooth brush type and an air hose with minor mechanical ability you can do it! |

Welcome,
Carbs are easy to rebuild, but the kits will have some extra parts, so match up with your existing parts. Other than that, I'm pretty sure the minor mechanical ability is unnecessary, they are that easy.

welcome! yes those are pretty simple carbs
if i were to guess just based on what you described... could be a shrunken or cracked gasket???does it start right back up? or do you have to crank it a lot or hold the throttle to the floor to restart it? |

It starts up pretty good for a 45 year old car. It has to crank a little but it starts up and runs strong after that. Would it be better to invest in a newer carb like a 4barrel or rebuild the existing one?

what i meant about starting...was after it stalls?
yeah it shouldn't cost much for a rebuild kit for your carb, try that if it doesn't work out , then you could always buy a 4bbl carb/ manifold later |

It starts right up after it stalls without a problem.

Starts up and runs fine. Idle is alright while in park and while at a stop light. Previous owner had an alarm on it but that is unplugged and the wiring will be gone through and removed for it. Like I sis don't in the first comment it seems to run a little rich. That's why I thought carb

hmm, could be just some minor carb adjusting, maybe check some basics...are you running a points type distributor? if so maybe check the points gap (0.18") check the timing if that stuff is correct, then you can rule out ignition, then maybe check for any small vacuum leaks around the carb, make sure the bolts and screws are snug, spray around the outside of the carb with brakekleen/WD-40/carb cleaner...if you get any change in idle there could be a vacuum leak there. just some basics to check first

Stalling coming off idle at a turn, Idle circuit issue in carb, or accelerator pump/power valve. Stalling when shifting into park also sounds like idle circuit. Engine at idle, (running on idle circuit), shifting into park takes load off, engine should pick up rpms. When turning from stop, carb switches from idle circuit to main venturis.
Does the car run good except these times? I would clean out the carb. Unless... has the cars been sitting for a while and running on old gas? Edited by Big Bird - 20-October-2016 at 11:16AM |

It was sitting for at least a month or so before I purchased it. All the old gas has been run out of it for sure. Do you think it would be more beneficial to invest in a newer carb or rebuild the current one.

If you are worried that the carb may not be the issue, rebuild it. Clean it out and see if it helps. If you were thinking that you wanted to go bigger with the carb/intake, this is as good a time as any.
Problem with old gas is the ethanol now in fuel. It absorbs water out of the air, then the water/ethanol mix drops out of the fuel, forming a layer at the bottom of the tank. Fuel pickup sucks up some of the water and you can get droplets of water pretending to be fuel... Running on the idle circuit, those droplets can be problematic. Boaters call this problem "Water Bottom".

So it's sounds like a possible carb issue which is not a problem. I may change the carb but will definitely clean the gas tank and take a look at the fuel lines.

in regards to your thoughts of rebuilding the original or upgrading to a 4 barrel and intake... what is your long term goal? if youre wanting to go with a bigger carb and intake in the future, than get started with that notion now. if it doesnt matter one way or the other to you, than go the cheapest route first, which would be to go through what you currently have and freshen it up a bit. either way, whether its a freshened up carb, or an upgrade to a bigger one, you will be happy with both...depending on what your long term goal is with the car.

I appreciate all the help from everyone. It gave me a couple places to start. One last thing for a while hopefully.... The "alt" light comes on after about 5-10 minutes of driving then turns off after about 2 min. I just replaced the voltage regulator and the alternator doesn't look extremely old either. Is there any direction I could be put in to fix this as well. There is an aftermarket alarm system as well as an aftermarket radio.
Thank you guys again. |

go to your nearest auto parts store and have them test your alternator while the engine is running, that would be the first place to start, and it doesnt cost anything. or if you go to tires plus or firestone or places of this nature, for 10 or 20 dollars they can give you a more comprehensive alternator/battery/charging system test and print out with recommendations of the diagnostic. me, if i dont have the time, or if im too lazy, or if i just plain dont have the ability to diagnose something, i go have them inspect it for me, than i go about fixing or replacing what needs attention.

I had the alternator tested and it was pulling too many amps. Which led me to replace the alternator regulator.

what do you mean it was "pulling" too many amps? what was it putting out when you tested it?
if it was pulling, than something was drawing current from your system, if it was pushing, than it would be overcharging your system. |

With no load it was tested with 17.5 amps. With a load it was tested with 15.7 amps.
