I just rebuilt my carbs for my six. I got the car warmed up and started tuning them.
First when I turned the mixture screws on one of the carbs the idle did not change unless I just about turned them all the way in. The other carb did not change much at all when I turned the in or out. When I tried to adjust the air correction screws on both carbs I could not get them to all read the same on the sync tool. I was geeting a lot of backfiring thru thru the carbs. What is my problem here??????? |

I just did this and found that "much" of what you're talking about can be cured with new vacuum lines all around. Mine still had all the factory braided cloth stuff. Next use the carb cleaner method mentioned above. You're popping does sound like a lean condition. After 35 years, you'll probably need to have new shaft bushings. I recommend Harry Beiker at:
www.biekerengineering.com There is also a factory fix for the shaft bushing (has a factory number and all), it's a special tape precut that wraps around the shaft. I may have one laying around somewhere with the part number. (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif) |
