FORUM RULES: Users agree to these Rules when using Forum.

The site administrator reserves the right to change the terms and conditions of the user agreement without prior notice to the user. It is the responsibility of the user to regularly review the terms of this agreement.

The user agrees to the following terms:

All information that you provide to us for your membership is correct.
You will not use your membership to spam, harrass, or exploit other members in any way.
Vulgar, Abusive, Racist and Sexist Language will not be tolerated.
Commercial-type sales postings will not be allowed.
No mass posting or flooding of the boards is allowed.
No Advertising of parts or cars; no Ebay or business/commercial ads (please use the "Classified" for ads Wanted or For Sale).
VIEWING MULTIPLE TOPICS ON SCREEN: You can choose to see more than 10 Topics at a time ... Log In and choose "Preferences" from the top bar on the Forum page. Scroll down and Change the "Default Topics Returned" parameter to 25 or 50, and save the changes. Since this setting is stored in your browser 'cookies' (if enabled), it seems to use that stored value even if you are not logged in. So, if you use a PC that you haven't logged into the forum from, the setting still seem to remain at the default.
EXTERNAL PHOTO LINKS ON FORUM: You can still use external photo links in your posts on the new forum. They follow the rules of any link in that they have to have the URL link qualified down to the full image file name (example: .jpg). The links will open in a new browser window, the same as an uploaded image attached to a post. Since an image attachment to any post does not display inline with the post, the results are the same. You can use multiple external links within a post. This link is from photos on a site from Don Clink's 'Deuce@75' albums:

http://donclink.com/deuce_75_1/images/dscn2950.jpg

Using links from photo sites such as Photobucket can help in "size" issue with uploaded attachment files. For best viewing in web browsers, photos should be around the 800x600 pixel range, and probably not more than 1024x768. Most cameras today store HUGE jpg image files, as the default settings are in the 7, 8, 10, and 12Mb image sizes. The image files that are then attached are very large, and the browser can't display the full image size without using the scroll bars. Use the re-sizing functions of your photo editing software to reduce the image to 800x600, which reduces the file sixe and the image load time in the browser. Don uses Google's free Picassa3 software, which is an excellent photo management product. All of the photo albums of the Deuce, Grand National, and Auburn that are links on the NORG site were built using Picassa's web creation functions. And it's free? (THANKS to Don Clink for the info!)

Anyway you look at it, the addition of alcohol to gasoline has not shown to be a benefit, except to the corn growers. Now that the tax subsidy has been eliminated, and the price differential gone, the producers have been left high and dry (no pun). Most gasoline has become contaminated with alcohol, even when it is not supposed to be. Old vehicles, lawn equipment, and other uses, have been damaged in the pursuit of "energy independence".

There are thousands of gas stations in the U.S. and Canada dispensing fuel w/o ethanol. Check pure-gas.org for those in each state or province. - Roger J.

The problem is the cross contamination caused during the transport of alcohol and alcohol gas. This has caused detectable levels of alcohol in almost all gas. Alcohol must be trucked, as it corrodes pipelines, and when there was a tax subsidy, some greedy station owners filled their regular and premium tanks with gasohol to increase profits. Alcohol is hygroscopic, attracting moisture. At our shop we test fuel when a vehicle comes in with fuel problems to see how much, if any, alcohol and water are involved. Gasohol undergoes "phase separation" in storage. This means as much water as gasoline may be pumped into your car. Gasohol is ethanol, while the treatment for contaminated fuel is methanol, sold under the name of "Heet"' DriGas", and similar names. Unfortunately, it is virtually impossible to find gas free of ethanol.

I wonder how a flathead would run on E85 if all hoses , seals ,and gaskets were changed and all filters could tolerate the high alcohol levels? Has anyone ever tried it ? Its probably just a matter of time before we are all looking for ways to run our old flatheads on whatever the gas stations are selling.

I have run flatheads on 100% methanol, and mixtures of methanol and nitromethane. Ethanol poses no particular problem in relation to the above, but in all cases, it's a good idea
to "purge" the fuel system (carburetors or injectors) of the above listed fuels by running
on gasoline before you store the engine to avoid corrosion and gummy residue. As a day-to-day fuel, of course given alcohol-proof fuel delivery components, there is no reason that a flathead wouldn't run on "E-100" if that's all that was available. You would notice a substantial decrease in mileage, you would need to crank-in a lot of advance. You would benefit by increasing the compression ratio (a lot!), and you would need to run an alcohol-compatible lube oil such as Kendall Nitro Plus. Lets hope it never comes to that. The upside is you will have no detonation, and a cooler-running engine, that makes
more power if you have made the previously referenced modifications.

How about the various additives available? Any recommendations? What's with all the hype about Techron?

I believe "hype" is a good term. Over the years, we have seen many "miracle" additives promoted. Remember "Slick 50"? It is tempting to believe that pouring some mysterious (and usually expensive) stuff into our engines would fulfill some apparent lack or boost life or performance. It made fortunes for the promotors, but few, if any, survive the advertising blitz. We would all like an effortless "quick fix" that bypasses the reality that things do wear out, just as we hear of "the carburetor Detroit supressed" that would give us endless gas mileage improvement. We are seeing amazing advances iin lubes, such as full synthetic oils that extend drain periods for longer periods while protecting expensive engines, but you can bet that they are a wiser investment than a bottle of some "secret" potion.

Techron is a trade name for a fuel system detergent and gasoline mixture. It will not help with the problems with old ethanol/ gas mixture.

Fuel stabilizers inhibit the breakdown of the gas into varnish and corrosive elements and should be used if your car sits for more than 30 days. For longer periods of storage, you should also use a stabilizer or drain your tank.
