Pump Return Spring - 66-15

Glad I ordered the spring, the one in the carburetor was very thin and weak.

The return spring is of good quality and excellent fit.

I had my '57 Chevrolet WCFB carburetor rebuilt by a professional carburetor rebuilder a year ago and it was acting up when I got it back, and so I took it apart and noticed that the accelerator pump return spring was incorrect. I contacted Mike's Carburetor Parts and they sent the correct part right out to me. I've also had the pleasure to talk with Mike over the phone as well as one of his staff members, and they were both very courteous, helpful and responsive to all my questions and concerns. I would certainly go to Mike's Carburetor Parts again, should I ever need carb parts. THANKS again, Mike and Staff! --Dan Collier, Laughlin, Nevada

Good quality spring. It got me up and running again. I had the wrong return spring from whoever rebuilt the carb before me. This spring was the fix.

I was very happy you had the part and delivery time was good

Great site, parts, service and delivery.

Bought a few things from mike they were prompt to inform me of shipping details along with reasonable pricing .As a person new to old carbs i found mikes online videos super helpful! I will purchase from him again and i would recommend him for Carb parts👍

Fast shipping great parts!

Great product, very friendly and knowledgeable help.

Could not find this part at the local part stores,so I ordered 2. I was shipped one long and one short pump return spring? I used the short as the long spring was in my carb,and would slip over the pump cup! So far so good!!
