Thanks for the reply. I have confirmed that there is spark on the font 2 cylinders, and the spark is strong there. I haven't done each cylinder separately though. Will have to try that. I have tried starting fluid, and brake clean, but it wouldn't event try on that. I have had the best luck using 2 stroke gas mix, but mostly all it will do is start, stumble a bit then die. After that, all It will do is hit on what I believe is the strongest of the cylinders. I will take a look to make sure all the plugs are getting spark, and if not, dig into the distributor.

A start and a stumble is great progress! Do check that all cylinders are getting a spark, but also suspect that the reason it does not keep running is that the carburetor needs service. After cranking a bit, peek down into the throat of the carburetor; have someone pump the throttle to the floor a few times. Each time you should see the accelerator pump squirt a nice little stream of gas in to each barrel of the carb. If no, we will advise on how to work backwards from there to find out why the carb is not getting fuel. If yes, the situation is more complicated. Could still be ignition; could be carb main jet path gummed up. |

I was blaming the carb at first, so that's why I replaced it with the Stromberg knockoff from Speedway. I also rebuilt the fuel pump with a NapCo kit from 3rd Gen. The gas tank is, in my opinion, beyond repair, so I have been running a hose from the pump to a gas can. It pumps good and the squirters in the carb are working. I have also tried to bottle feed it, also with no luck. It seems to light off quickly but then stumble and Die. The ignition switch was bad when I first tried to start it, so it is wired through a toggle switch, and has a new ballast resistor as well. With a 6 volt battery I have seen a consistent 6.3v at the coil every time I have checked it. |

I agree with others, send distributor to Third Generation. I would not try to work on one of these distributors myself. No timing marks on the engine to set the timing. Ford designed these distributors to be easily removed, work done on the bench, timing set on a machine, then bolted back on the engine. With new points and timing set by a pro on the machine, your distributor will be good to go for years. |

I can not argue wit those recommending a distributor rebuild, but I will note that I bought three 97 carbs from Speedway. The float was way off on all three, and one had a casting flaw that completely blocked fuel flow to the primary jets. That flaw would let the engine start and then die. Can you borrow a known good carb? |
