Re: Roadster getting harder to start
Does it start OK when the engine is warm?

Re: Roadster getting harder to start
Katy - yes, once it's warmed up it starts again just fine.

Re: Roadster getting harder to start
Since it only does it when it is cold I would suspect the choke plate is not closing properly. If you crank it for a bit with the choke on do you get gas at the carb throat?

Re: Roadster getting harder to start
Do you have a fuel filter either in the tank or in the sediment bowl (or both) that might be restricting flow?

Re: Roadster getting harder to start
We had a fellow join our "A club a few years ago who had the same problem. It turned out to be that he knew enough to turn the choke to make the mixture richer, but no one had told him that the adjusting rod was pulled out for a cold engine start.

Re: Roadster getting harder to start
The problem with the carb being the issue is that it was this way before I rebuilt the carb - and we went through it very thoroughly because the car had been sitting for quite some time. There does not seem to be any issue with fuel - again, it's fine once it starts and will restart just fine when warm. I will try the idle screw though.
As for a fuel filter, no, neither have them. just the sediment bowl. The GAV has been turned out about 1.5 turns (and many points in between) trying to see if that is an issue. It does not seem to be. That said - thanks for the ideas. I'm going to go through most if not all of them this weekend! |

Re: Roadster getting harder to start
From the comments I suspect a Crack in the intake manifold or it's warped. The engine is pulling air when it's cold. Warmed up the Crack will close up.or the intake gasket is leaking. I've run into this situation a few times. If you are using a Tillotson carb,put a second flange gasket on it.
Every A. That I set up can sit for months and with Just a pull of the choke for one revolution then release it,fires up and starts to idle. When warm just bump the starter and it starts. Good luck Wick |

Re: Roadster getting harder to start
Be very careful with that stuck dist. That base will break right off and leave you with a mess. Don't pry too hard.
Just put a new manifold gasket on. Easy and cheap. |

Re: Roadster getting harder to start
What spark plugs and gap are you using?

Re: Roadster getting harder to start
When you try to start it cold, first have the coil wire 1/4" from a head bolt to make sure you have a strong blue spark. Even new points can have continuity problems from oil or hands touching the contacts, dirt, etc.

Re: Roadster getting harder to start
Years ago (60's) with my first 'A', I had trouble starting it cold. An old guy reached into the cockpit and pulled the hand throttle down close to half way and said 'crank the damn thing'...and guess what? The damn thing started! Then he quickly closed the throttle to a bit above normal idle and that was it. To this day, I set the hand throttle and the spark before I start the engine...Just a quick pop on the choke rod.
