Well I by-passed the base plate and ran a hose from the base plate up to the front of the car so some air should go through the base and help to cool it down. Of course as soon as I got it done it started to rain and since the under carriage has been all detailed I'm not going to get it all dirty. Hopefully tomorrow will be better.

to get more air into the engine. granted with the adapter you would be limited slightly to the amount of additional air.
nope, the 250 used the same head design as the 144-200, unless you can find an aussie 250 2V head. those have removable intakes. an argentine six also has a removable intake, and those heads als bolt to our blocks, have to use a different exhaust manifold though.

I have a Holley 1bb on my 63 Merc Econoline 170... it does exactly what you originally said... I called the previous owner, and he told me "stuck float needle... give the carb a couple taps with a hammer to free it up." Voila, that's what it was! I need to rebuild/clean the carb, or use my Autolite from my donor vehicle. Sorry I didn't see this sooner.mannella":zic49j50 said:the carb on this car is a holley one barrelsixpony":zic49j50 said:Just out of curiosity I'd like to hear some input from the guys running the two barrels, direct mount or adapter, as far as I have seen the little autolite 1100 is the only one that has this problem. What about the holley 1bb?
Great minds must think alike, yesterday I tried to find what the boiling point of gas was and found it was between 100 and 400f so these figures didn't help much. As far as a stuck needle valve this is a new carb (not that it means much) but I observed the fuel pulsating in the fuel filter and what I assumed was happening is as the fuel in the carb elaborated it would open the needle valve and allow more fuel to enter the carb of course the float would shut the supply off and then this would evaporate and the cycle would continue until there was no more pressure in the line. this would now cause the car not to start because it would be just like running out of gas. So as soon as I put some gas down the carb the car would start right up.sixpony":3cpv65fy said:One thing maybe worth mentioning is the ethanol content of todays fuel, I believe alcohol has a lower boiling point and this probably doesn't help the situation. Can fuel without alcohol even be found today? Sad to say I shop for fuel by price, not quality.
I'm happy to say that today I took the car for a run after I bypassed the carb base and ran a hose to the base to allow air to pass through it and I had no problems. The temp was the same as the last time I took the car to town and it wouldn't start. Hopefully its the last of the problem. I am looking for headers if anyone knows where I can find some. I would like to thank everone for they're input.--Lenny

In Ohio, I'm pretty sure I can. As long as all the other marketing ploys that are supposed to 'clean' the fuel system and boost economy don't have ethanol in it.
Out here, there's several filling stations that have 100 octane unleaded and 110 leaded in the pump. CAM 2 or equivalent. It's pricey but it smells sooooo gooooooood.

8) alcohol itself boils at 173 degrees, gasoline much lower than that.

There are quite a few other factors involved ,www.faqs.org/faqs/autos/gasoline-faq/part1, a lot of this is too techy for my laymans brain but I did discover that fuels are actually rated for vapor lock and there is a lot more difference between brands than I would have imagined, may have to rethink my buying habits! Congrats Lenny on solving your problem thats one of the joys of these old cars ,the sense of accomplishment when things work out right.
