Hello, I have a 38 Master Sedan. I am having trouble with the fuel feed, so I'm looking for a carburetor rebuild kit. I went to this site:
http://old-carburetors.com/Chevy/pages/016-Chevy.htm
and decided I should have a Carter 391S, but my carb doesn't look at all like the one pictured there. And I can't find that 337.
But in the back of my carb, where the choke connects, it says Rochester. On the front, I have these numbers: 70002105; F41; K127. Does any of this make any sense? Did somebody swap out the Carter for a Rochester? Which number is the Rochester model number?
By the way, the fuel delivery problem developed after I bought the car--last winter, I let it sit in my garage for maybe 6 months without starting it. Help.

Welcome to Chevy Chatter II! Glad to have you with us!

Yes, your car should have a Carter W1 Model 391-S. Without looking up the numbers is sounds like you have a much later Rochester replacement....which is not the correct carburetor for your car. There are kits available for your Rochester if you want to continue to use that carburetor on your car.

Letting a car sit for six months without stabilizing the gasoline is not a good idea because with the lousy gas we are getting that stuff will contaminate the fuel system after sitting for many months. End result, the car will not run correctly. Most likely you have some dirt in your fuel system which found its way into your carburetor.

Thanks. Do you think I should start looking for a Carter carb? The Rochester seems to have a pretty bad reputation. But I had one on another car years ago, a 67 Camaro, and I didn't notice any problems there.

If you want the car all original then you might want to have the orginal carburetor. However, if it is just a driver and you are not going to have the car judged then you might want to stay with the Rochester. Basically, it is up to you as to what you want to do. However, if it were my car I would opt for the original carburetor.

Having said that, you should be aware that the 1938 carburetors are kinda sorta expensive so be prepared to spend some bucks when purchasing the original carburetor and having it rebuilt.

Thanks again, that was a lot of help. I think I'll sign off now and start looking for a Rochester kit.

Ya, at least that way you can get your car going again until you decide if you want the correct Carter carburetor or not.

Also, check with the Filling Station on the Rochester kit. They have them listed in their catalog. Go here: www.fillingstation.com

Good luck!
