If I drive my car and it's up to normal temp ( a little less than 3/4 on the gauge,) and shut it down-It will start instantly- if I restart right away; but if it sits for 20-30 minutes, I have to hold the pedal to the floor to start it and it starts right up! Then I I rev it, and it revs smoothly ; so it obviously wasn't flooded.What do you think the problem is?? Accelerator valve leaking a little and getting to much fuel in the intake manifold?? if it is that valve can I cure it by driving it more?, or do I need a new accelerator valve? It was okay about 3 weeks ago;sat at a car show for 2-3 hours, and started almost instantly, but that's the last time it was driven.

How about some more info. What carburetor ? If you have to hold the pedal down to start it is a sign there is too much gas in the intake or cylinders or flooded. If your running a 94 I would suspect either a leaky gasket or leaking diaphragm on the power valve. If a 97 Carb. it could be fuel pressure or float level. Got an electric fuel pump? One Carb or multiple?

Single Carburetor , on a stock flat head V 8 with only the stock fuel pump. It was new about 1 +1/2 years ago. I believe that it is a carburetor originally made by Ford, and reproduced by Carpenter. Part 8 BA-9510-N. I meant economizer valve in my original post, NOT accelerator valve. It doesn't seem to flood, but I think your right, it's bleeding a little gas into the intake somehow. How to fix that? New gasket on that valve? A little Permatex on the gasket??? Those are my ideas; How say you?? It's been sitting over night night, and I just got in it this morning, turned the key on, and hit the starter button, (with my foot off the accelerator pedal, and no choke), and it started instantly!! Figure that one out??? Regards, Steve Lee

Steve, what you describe is not a problem at all. This is how it's been with carbureted cars of any make for as long as I've been on this planet. I even remember my mother doing that on her old Dodge Brothers sedan.

If this starting problem is something new and you have not had it for the last 1 1/2 years then you could try remove the top of the Carb and fill to a measured point with gas wait 20 minutes and see if the fuel level changes. If it does it would appear the economizer valve or it's gasket is leaking. Do not use any gasket sealer on the gasket for the economizer valve. Daytona parts sells a fairly good rebuilding kit for the Carb. or send the Carb to Charlie Schwendler see V8 Times Services section of classified.

This carburetor wouldn't need a rebuild, just that gasket. Does anyone know where can get just that part if I find that's the problem?? And, why doesn't it do it the next morning if that is leaking?? It used to start after driving it, and it sitting for a short time -with no gas pedal, on the first SHORT crank! (About 2 seconds worth!)

hi I have a thought, maybe the gas is boiling and flooding the intake,?when hot, after it sits, opening the throttle when restarting will help with this problem, this new gas presents new problems, it also could be a coil problem. hot coils short out, after it cools then then work, how is it running for a long drive, looses power ? my 2 cents 37RAGTOPMAN

I have the answer most won't like. The starter itself is not cranking as fast when the engine is hot and has sat. The field is weak and a new or rebuilt starter is in order.

! don't use that ethanol CR*P!! I only use real gas in my classics to prevent all of those problems folks have with with Ethanol. It's more expensive, but in the end it's really cheaper.

It is a problem. In 1955, when I was 18 years old, I had a 1950 Deluxe Tudor sedan with a 239 V 8, and it never did that; This one never did either, until now, so something isn't right .
