Early Ford V-8 Club Forum

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:

  1. All information that you provide to us for your membership is correct.
  2. You will not use your membership to spam, harrass, or exploit other members in any way.
  3. Vulgar, Abusive, Racist and Sexist Language will not be tolerated.
  4. Commercial-type sales postings will not be allowed.
  5. No mass posting or flooding of the boards is allowed.
  6. No Advertising of parts or cars; no Ebay or business/commercial ads (please use the "Classified" for ads Wanted or For Sale).
  7. 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.
  8. 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!)
  9. HOW DO I SHOW MY EMAIL ADDRESS ALONG WITH MY USERNAME? You can LogIn on the Forum, and select PREFERENCES. On this page Members can add optional information such as their City,State, Country; Occupation; Hobbies: list a Homepage; list AOL Instant Messanger Handle; Signature; "Make Email Address viewable to others;" and even change the number of Default Topics shown on a page. WHEN others click on your profile, they will see this information.

Daytona parts has a kit for your carburetor. That is not an easy carb to rebuild. Be very careful to tighten the screws just enough to close the lock washer and alternate sides when doing this. You do not want to warp the dicast. Set your choke to the rich side and see if that helps. If it does, you have a fuel delivery problem. Watch for fuel dripping from the upper chamber, if you see some the carb needs rebuilding or replacement.

Check your dwell at all speeds it should not vary more than 1 degree. If it does, the bushings in the distributor will have to be replaced.

Do a cylinder balance test at about 15oo rpm. Short out each plug and watch for a rpm drop. All cylinders should give the same rpm drop. If one or more cylinders have a smaller drop, check the plugs and compression.

Dribble some MMO down the carb, you may have sticky valves.

Vacuum gauge readings would also help diagnose the problem.

Mike, What hasn't been addressed by anyone so far is the flex line from firewall to pump. They tend to collapse internally, causing a restriction that impedes flow, sometimes just enough to cause a miss like yours. Bob Shewman has fuel resistant flex lines: 610-993-6637

Hey guys ,back again. With all the things I’ve checked I’m thinking the carburetor might be my problem. Maybe a clogged fuel passage or I’ve heard it may be a power valve? Any ideas on where to get a rebuild kit ? I probably should have mentioned this before, this problem happens when engine is hot or cold,it will rev right up but breaks up when you try to hold the rpms steady.
Thanks for any and all help mike.

This message is to all who responded to my problem. Coil wire and all 8 plug wires show a good whiteish blue spark at about 1/2 inch from a good ground. Fuel pump delivers a total of 8 ounces of gas as per the instructions given. No kinks or obstructions in line from tank to carb.the one thing I forgot to say about my problem is that this condition happens whether engine is cold or at running temperature. I am thinking now that my problem could be in the vacuum advance and or the source of vacuum at carb, or the carb itself as mentioned in the responses to me. Going to put this mess on hold, going to where it’s warmer for a few months and tackle in the spring .thanks to all who helped out ,it meant a lot to hear from you all. Mike

Mike, another thing to check is the primary wire inside the distributor. The insulation could be bad and the ignition shorting out when the advance moves the point plate.

car crazy, thanks for helping. The wires appear to be copper strand soldered at both ends of the wire. Fuel pump tested at 3to4 pounds pressure at idle and when at an rpm to make engine miss. I will check volume of pump next .thanks. Mike
