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:

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!)

Are you sure you have vapor lock? Many times a bad coil or other ignition problems can give similar symptoms.

I'll bet that at least 80% of "vapor lock" problems are actually bad coils!!

It is not hard to tell the difference between no or weak spark and lack of fuel . I personally use champion UD16 plugs because they have a hollow center and you can see spark in there as the motor runs . Really handy to diagnose most ignition or miss issues by simply looking into the plugs . If you have distributor or wire issues it shows up real well . Yes coils & condensers can cause symptoms similar to vapor lock but again it is real easy to tell if it is spark or fuel supply issues . AND the person asking the question asked about " vapor lock " NOT ignition problems . As I posted before simply using non-oxy gas is all I do and I have no vapor lock issues . This is stock 33-34 cars only and yes the ignition stuff is in good order .

David J,

It is not necessary to get testy, because someone tried to give V8JR another item to look at besides your answer.

V8JR did ask for for any thoughts and TRJFord8 gave him a valid answer to his question.

Testy ? The intent was-is to point out that checking if the " vapor lock " issue is fuel or ignition is REAL simple and takes about 5 seconds to verify strength of spark at all 8 cyls . That is if you are using UD16 plugs . BTW they cost no more than regular plugs [ well last time I bought a few boxes anyway ] and really work well for checking spark at all 8 cylinders . Now that is useful info and gets you on the right track in seconds . Non oxy gas cures all else for me anyway . David J

On our 2013 cross country tour to the GNM in Lake Tahoe, the majority of our cars experienced Vapor lock quite frequently on the 90°+ days, at the higher elevations, using the 10% alcohol enriched gasoline. We had about 20 Flathead powered cars from '32 to '53 on this tour.
I knew the VL problem with my '35 fordor was not caused by ignition issues. I could see the alcohol in the gas boiling/bubbling in the glass bowl of the fuel pump. This caused a pressure buildup in the line that the fuel pump could no overcome.
I carried ice water in the cooler strapped to my luggage rack, and whenever VL occured I would place an ice water soaked towel on the fuel pump for a few minutes. After this, the engine would start as soon as fresh gas was pumped into the carburetor. This worked every time.
Those who had backup inline electric fuel pumps would just flip them on for a few seconds, and then be on their way.

There is an advertisement in the V8 Times for a fuel hose with a built-in check valve. This would seem to prevent draining of gas from the carburetor. This may be an easy fix compared to installing an electric fuel pump to prevent carburetor drain. Has anyone tried this approach? Would appreciate thoughts.
