I do understand the criticism of the "quick start" bypass. I've installed them for years. They cost almost nothing, and almost always decrease starting problems. All cars, without exception, accumulate problems from the day they leave the factory. Batteries age, starter bushings and commutators wear down, and wiring, and connections lose conductivity. Most owners don't want to, or have the ability, to constantly repair and replace these items. They just want their cars to start every time, hot or cold.

Supereal many thanks for your advice re installing a diode to help hot starting. I have in fact installed it and not only does it start when it is cold but also appears to start instantly when it is cold. So all good, really appreciate your words of wisdom, no doubt I will be back to you on some other matter if that is OK. From New Zealand. Cheers Mike.

Thanks, Mike. Always happy to help where I can. As I have mentioned here, the car companies used a similar circuit back in the six volt days, so it isn't a radical change. Had solid state diodes existed back then, it is a sure bet they used the same setup.

I'm having the same problem,I'm thinking fuel also. Years ago I saw a spacer (approx. 3/4" ? ) between carb and manifold, made from a non-metalic material. I was told this was to keep heat transfer from getting to gas in bowl of carb (boiling gas)I'm looking for one, might have to make one or if anyone knows if someone makes them, comments on this thought please

Carb insulators are of questionable value. Ford did just fine for all years. Boiling gas is only a problem when the engine is stopped after a long run. The "heat soak" can evaporate fuel, but a properly operating fuel pump will quicky refill the bowl. The carb bowl hold only a small amount of fuel.

Fords4me, Have you considered that your engine might be flooded due to a leaking power valve. Try flooring the pedal when trying to start it hot. Check to see if you are getting gas by operating the accelerator while looking down the throat of the carburetor. Check all of the spark plugs for a wet condition or a sooty black condition. If the above are all OK check the spark when hot. I agree that the spacer is a profit item for an enterprising man. A profit item is defined as something that looks like it should be good but does absolutely nothing. The spacer is a useful as the turbo fans that mount under the carburetor.
