Correct method of starting a 390 c.i Engine

[dan reed]

Like someone mentioned earlier - I too installed an electric fuel pump on my '56 Caddy. Even when I completed the carb rebuild it still needed a few pumps and turns of the key before it would fire up (this is after sitting for a week or two). With the electric pump it gets fuel up to the carb quick and will start right up. Electric pumps aren't expensive and its not hard to install. I'm sure I paid less than $70 total for everything needed to complete the job.

Can  anyone tell me why I ,a PAID-UP MEMBER IN GOOD STANDING,MUST GO THROUGHT with the requirements of
furishing my name and email address each time I want to answer a post?  Now for my comment. It seems to me that if the Ethnol vaporated right away wouldn't that leave one with unllead fuel???

No. The two components are not like oil and vinegar in salad dressing. They do not separate when left to sit.

They are fully blended and become a new substance that shares the qualities of each of it's component parts.

Hi Guys,

Thanks for all your help, but your now getting too technical for me it seems that if you find a method that works use it. So will it be O.K to use this below yes or no :-

When I went to buy the car the dealer got in it pumped / banged the accelerator several times ( couldn't see what his foot was doing but I suspect he had some pressure on the pedal ) it cranked over fine but did not fire, he did the same procedure again and it started it was running for say 60 - 90 seconds, then he gave it a couple of revs and it settled down.

Forrest. The Ethanol blended fuels will seperate to some degree. The Ethyl Alcohol evaporates at a faster rate than the gasoline will. A 10% blend, which is the industry standard for pump gas contains a RON of 82 for a regular grade. The introduction of the 10% Ethyl Alcohol, brings the substandard 82 RON up to the minimum sold at the dispenser. Leave the cap off of a 5 gallon can of fuel for a while and the octane rating, if tested at a lab will be substandard to what is required in retail sales.

Premium grade (93RON) is really just regular gasoline with the Ethanol added to make it 93 RON at the pump.But there still is good old regular 87, and premium 93 without the Ethanol available. But it's sold as recreational gasoline in some states.

Damn! That $hit gets worse and worse every time I hear about it. Truly it's designed specifically for pressurized, fuel injected systems.

Now I will assume that it doesn't separate per se. That is, there won't be two distinguishable layers visible in a lab flask if left to sit. I figure each molecule of ethanol must evaporate on it's own from wherever it is in the mixture of gasoline. If it separated like oil and vinegar it would be doing that in gas tanks and storage tanks, etc.

Either way it's freaking mess. We can't obtain ethanol-free fuel anywhere in metro Atlanta by federal mandate.

I wonder if the ethanol could evaporate out of the carb leaving behind the 82 octane crap and make it hard to start?

What does 82 RON equate to using the AKI rating on US pumps?  (RON + MON) / 2

I knew you would catch on eventually.

Corrrect.

Correct again.

Ding, Ding, Ding. A three time winner !!!    Seriously, it is blended at the truck loading rack. Where I load, each loading arm loads at the rate of 650 GPM. A secondary injection system injects the Ethanol at a rate of 65 GPM. Should the computer detect and incorrect blend it shuts down and has to be reset and the blend ratio self-corrects.
Either way it's freaking mess. We can't obtain ethanol-free fuel anywhere in metro Atlanta by federal mandate.
You should be able to buy it an any big recreational area, or a Marina that has a fuel dock. I can get it here, but it has to be put into legal gasoline containers, and not directly sold and dispensed into an automobile. It still has all the state and federal taxes levied on it. Just no Ethanol.

I wonder if the ethanol could evaporate out of the carb leaving behind the 82 octane crap and make it hard to start?
It is a possibility. I let my '59 run out when I park it by shutting off the fuel pump. And the Eldorado gets used too much to bother with doing that.

I honestly have no idea about that. Any public gasoline dispenser has to label the research octane number of the product it is dispensing. You're the Engineer....You should know that. And so should I.

Maybe we should all go out and buy a boat, fill up at the Marinas, then siphon out into containers and decant to the carburettored car?

Now taking orders for pure Atlantic Canadian gas . . . no ethanol here.

IF BLENDED  gasoline is allowed to set , will it leave  UNLEADED gasomine in the tank     JIM
