On my '66 De Ville both of my turn signal indicators do not work despite that the regular turn signals work front and back. . I'm thinkiing that they are on a separate circute rather both are burned out at the same time.

Any thoughts

Check bulbs, usually it’s a grounding issue clean the grounds on the lamps make sure they are cleaned.

Trace the wires coming from the lamps ,you’ll find the grounds, if that don’t work trace the wires back to the steering column, switch etc. 

Thanx for your reply. First of all I mistakenly indcated that I have a '66 when actually it is a '64. 

Turns out I underestimated the previous owner because when I removed the left side indicator from the fender the wire was broken off at the recepticle. I'm guessing that the right side is the same. I had thought the the fender indicator lights were operated by a completely seperate relay system like my '66 T-Bird.

Cheers

Edelbrock Carb Block off Plates

Posted by Chase on March 12, 2025 at 2:05pm 14 Comments

Hey guys,

I have installed the same Edelbrock carb and have done everything the same as Jason’s carb and intake project. In the spring and summer months the car starts, runs and idles great! In the fall and winter months on a cold start, the car starts awful and wants to die until it warms up. I have to keep my foot on the throttle until it warms up or it will idle just terrible and try to die. Once it’s warm, it runs fantastic! Whats going on here? I was thinking of removing the…

Loud air moving sound within carb with cleaner removed

Posted by Dave Fehrle on March 23, 2024 at 3:23pm 8 Comments

While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?
