Hello Olds fans.
Please allow me to vent a little.

I just dropped off my carb to be rebuilt by a local expert
and he said the carb body needed to be replaced, threads
are badly worn at fuel line/filter point.

1970 Cutlass convertible 3 peed manual on floor.
Original QB code engine with original 7040253 carb.

I have to try to find a replacement.

Or, just have a helicoil installed in the fuel inlet.

 

The fuel inlet repair has worked for 35 years..an expert would know that..take it somewhere else


I've had then fixed where they where so bad there was no threads even left

 

Thanks for the response guys. I mentioned a healicoil
and he said it won't last.

I'll try to find someone else.

it is a valuable carb..use a reputable shop...even with a repair..its valuable, its a hard carb to get..

 

Thanks to all for the direction, dropped off my carb today to everyday performance for rebuild.

Right here in CT.

Have nice weekend and drive those oldsmobiles!

Sweet car.

 

I know that you already dropped the carb off, but I just thought that I would put this out there for future reference. I had the same problem 2 years ago for my quadrajet. At the time, I did not have the time to send it out because I was up in PA (where I used to store my Olds) and needed to get it back home in Maryland that day.


At the local home depot I found a newer type of plumber's tape (yes, plumber's tape) that is made to be used with fuel lines. Exposure to gas does not affect it at all. A few wraps on the gas line and it was able to screw onto the few threads that were left on the carb. It worked so well, I left it that way for the rest of the summer, just to see how it would hold up. Passed with flying colors.


I wouldn't call it a permanent fix, but it worked so well that the tape is now a part of my in car emergency tool box.

 

chip, Thanks for tip.

When I pulled the carb there was some type of teflon tape
on the threads already. Thast when i knew there was a problem.

I should have it back this week.

 

Great looking car! If they do a good job could you post their contact information or URL.

 

Yeah, but that heli coil "won't last"


You will be lucky to get another 10-20 years out of it.

 

Let us know how it works out.

I've got a Q-Jet i need glass beaded and rebuilt for a stock ish 72, maybe I'll consider the guys in the CT.

It's between them and Hobbs in Pelham.


I've had bad luck with Edelbrock, tuned it way rich and it's almost there. But I need someone who can rebuild the Q-Jet accordingly.

 

JPC, please call Ken at 860-218-5780 Everyday Performance.

I'm sure he can answer your carb questions.

Dave

 

Thanks!

Please post back when you get your carb back, let us know how it runs and any issues, etc.
