10% Ethanol
Got a BG Demon to replace it. New carbs have the internals to stand up to the effects of the ethanol. Still going to use fuel additives to combat that junk.
Going to get the Q-jet rebuilt and box it with the rest of the stock parts.
Good luck.





Somebody has to craft a long term plan. The only entity that can do that is the representative of the people ie Congress and the President. Big business has proven they aren't up to the task because of the economic meltdown. You're saying big government intrusion had no part in this present mess????? They only think 30 days out and do anything they can get away with for a buck. Nonsense. No decent business has that short of a time horizon or corporate morality. There's a few bad apples, but you're painting with an awful wide brush.

I'll try to think more like an old washed-up TV repairman.

I think one of the problems is that you guys are buying ethanol from stations that have never had it before and the alcohol is combining with all the water sitting in the bottom of those tanks.
The rest of the US has been using ethanol for 30 years without problems. I remember filling up with it in 1980.

I dunno what threads/where you may have read about my rough running and crazy experiences here with water in the gas....but it's been a battle ROYAL over the last few years, finally culminating in running lo on gas, engine sputtered ans swallowed lord knows how much water.....
and Jsup got the injectors changed out for me, and so, then I stuck those old injectors in a stepson's van 318, and they run like a charm...the ones that did't idle worth a toot in the vette....
so, the vette has gradually accumulated the same rough idle right back again....damnit....seems the lower the tank is, the rougher it is....I think I going the marine oil/water separator trick, and try that, clean out all the crap....
I dunno you read it, but I pulled a tad over a gallon of water outta the bottom of my tank here about a year ago...
SOMETHING is greatly remiss, neither the Miata or the Escort loves things with a fine smooth idle.....IN THE PAST the Escort would respond with new plugs and wires....smooth out and run fine...
someting funky in Denmark, methinks....

Gene...your car would have pulled the water first. The water is heavier than gas and sinks to the bottom of the tank.
I tried starting the car after a long winter and found I was pumping water into the carb instead of gas. The water settles to the bottom, since it's heavier, and is picked up by the pump first.

it's Florida, and I spend 53 years in Maryland, outside DC, so I know about all that area pretty good, sis used to live in Shippensburg, just off I81 south of Carlisle....was nice for the shows, easy drive and snore.....
That was the funky part, that crap was on bottom of the tank, barely covering the sock, so with enough fuel slop or whatever action going on the engine SEEMED to run more or less OK, but lacking on power...the rough idle came and went as Hogan's Ghost......some daze it was smooth as that monitor screen, other daze it shook the car apart....I went nutz for a LONG time, when running it 'dry' a years ago....AAA home and found that crap in tank bottom, well, on went a locking cap and it's been fine up untill now,
here is the trick, I drive it nearly every day, but not all that FAR, it gets maybe 1-200 miles/week on it, if that....so ~once a month or so it gets filled up again....plenty of time for gas and ethanol or what EVER combines with ethanol...WATER....to separate out from the gas....
NOW, I certainly no chemist...but I know gas/oil products don't combine with water......I know that Alky does do water well.....
so, question is....how to combine my own 'ethanol' mix and let it set in the clear glass for a few weeks with a cover on it....
I want to see how/if it separates out, and what that sludge on the bottom of the jar IS.....
IF it smells like that crap outta my tank....a totally UNforgetable stink, and looks the same...like thin milk/coffee.....then I done proved my point AFAIK.....
so then to get a fuel/water separator from a boat in that fuel line, and see what happens....
thing is, I need a high throughput...as I have DPFI with a return line....only a 24 lbs L98/LT1 style engine, but still it has to have a high volume for the thing to work right....


The Best of Corvette for Corvette Enthusiasts
Much overlooked in most discussions about ethanol from corn are the by-products from the production of ethanol. In general, the waste product from corn distillation is DDGS, distillers grains, a protein-rich food. The vast majority of corn produced in the US and the world goes to feed not people but livestock, which cannot naturally digest corn. The main result of feeding corn to a ruminant is excessive flatulence (production of methane gas, being a greenhouse gas), but the same animal can can readily digest DDGS[citation needed]. Seen in this light, all corn destined for livestock feeding should probably be distilled to harvest the ethanol fuel potential while simultaneously making the feed more nutritious to the livestock and avoiding unnecessary methane pollution. Wherever corn is used to feed livestock, farmers can take advantage of this process to make a profit on both food and fuel from the same bushel of corn.
A Federal Government Sponsored study found a gallon of ethanol makes almost twice as much energy as it consumes while it also has the potential to cut greenhouse gasses by 54% if cars ran on ethanol rather than gasoline.
Bush's point man on alternative energy, Andy Karsner, predicts that the opposition to ethanol will fade over time. Karsner says that while the government is now supporting ethanol made from corn, by 2012 there will be technology to make ethanol from garbage, switch grass, and other nonfood products.

IF my cost per mile goes down, fine, but that is a BOTTOM LINE FIGGER.....SO IF they want to GIVE me a new ethanol burning engine for my olde tyme vette with newer engine, fine....I will take it and report back on the true MPG/cost of operation...
until then, they can go to HELL.....
maybe, IF we can make ethanol new cars, over time they maybe able to take over.....maybe....
I not hold my breath one way or another....

Case closed.
Case closed.
except our .gov is in bed with too many people, therefore no *****....
ME be prez....we have them ALL in 6 weeks or less....don't even NEED nuclear bombs....most likely....course there is that option for some Tack nukes....

be funny to watch 1.3 billion muzzies change cults in about 60 daze....or die....
their choice....
I presume you mean Rush Limbaugh??
I think our country will fall from within over this green weenie crap and killing the cars as transportation....much less our hobby...






I'm not a mechanic so I'm just going by what I was told. But I agree with you. The '75's Q-jet sucked. My new carb has made a world of difference.
Let start with the tank, ethanol is corrosive, need to change that to stainless steel. Then the fuel lines, like the tank stainless. Then the carb
anything rubber will harden and become brittle over time that will have to be swapped out for silicone.
Even after all this is done you still have to deal with vapor lock on those really hot days in traffic.
If your corvette was leased and you were handing it in three years you probably could care less, an you probably wouldn't even change the oil,
but if you own it you want it to last, hopefully another 40 years.
There's a price on his head for what he knows. Guess what Libs? Ever heard of the word "Revolution"? We know how to do that too. You might like the govt holding your hand, but alot of us don't. That means stay the f**k out of MY GD business! Is that message Lima Charlie?
