Runs bad
Stock except modern points/condenser. Starts fine and idles good. When I try to give it gas in the driveway, it back fires and stumbles. Timing is right, points are good. Any suggestions where to go next?

Re: Runs bad
Double check the basics incld fuel condition::
See if your losing spark or fuel... Condenser? I use an inline spark tester to monitor the spark or carb cleaner to richen it... Last edited by Mitch//pa; 10-11-2016 at 07:36 PM. |

Re: Runs bad
Aloha,
Had a similar issue, as soon I applied some throttle it would miss and die. It was a condenser issue. |

Re: Runs bad
Do you drive the car regularly?
Did it just start doing this with no adjustment, repair or replacement of any other part? If something was changed just before it started doing this, what was it that was adjusted, repaired or replaced?

Brian:
Make sure you have a good fuel flow from the tank. Remove the fuel line and see if there is a strong stream with the gas cap off. Next check your gas cap to see if the vent hole is plugged. If you have a repo 30-31 gas cap with a center rivet it can loosen up and the gasket and the large washer can rotate and cover up the vent hole. Tom Endy |

Re: Runs bad
Sorry a little more info. Not my car, but a friends. He has not driven for a few months. Good fuel flow, spark at points and coil wire. First time working on it yesterday. Pulled what little hair out and found the fuse holder was bad. Got that taken care of and today trying to work on the backfiring. Timing is good, plugs gapped right, points set right. Going back over tomorrow and not leaving till it is right.

Re: Runs bad
Sounds like the same problem this poster asked about. Re: Engine stumbles and dies
Turned out to be a blocked Main Jet. http://www.fordbarn.com/forum/showthread.php?t=203934

Re: Runs bad
I would check the condenser first. I had a similar problem and that was the issue. If not check your gas flow.

Re: Runs bad
I've found that most carburetor problems........ are cured by fixing the ignition. Points/condenser, possibly coil.

just had the same little problem on a newly rebuilt carb. found out i had to have the GAV open a whole turn for it to run right. so i guess thats where i would go first seeing that car sat for a while with more than likely corn gas in it. good luck Tinkirk |
