Does anyone have a picture or instructions on how to install the float assist spring on the number two style zenith model b carb? I am running a fuel pump on my speedster with duel model bs . The fuel pressure is set at two pounds. The carbs have started to drip gas out the over flow. The b carb have the rectangle (number two style) float with surge baffle. I have the book " The Rex Rehirs Way " . It shows a picture of the float and surge baffle , but not the spring installed . Any input would be helpful. Thanks Miff

Go to Vince Falters Ford Garage, he has some assembly pictures for the B carb, it shows the spring in a side view, it will help.

Brian T I went to the ford garage web page . I saw the parts lay out on the b two carb . What I need is a picture of the spring installed . I guess it's to putting the spring in . It can only go in two ways .thanks

If you have the spring it should be easy to figure out, I found this hand drawn picture, person unknown, maybe this will help.

Thanks I figured it out. the hook side of the spring fits around the float post.The straight side of the spring goes between the float and the baffel . Putting light pressure on the float that pushes on the shut off . Thanks for the follow up . Miff

These photos are of a new old stock B-2 zenith showing how the spring and the baffle and the float should look. The spring only has about a quarter turn of wrap when installed, it is very light. The spring is only used when the fuel system is using a fuel pump with 2 to 3 psi max.

The action of the spring is to "close" the valve - it compensates for the downward push of the valve disk under pressure from the fuel pump.

I.e. If left in place on the Model A it causes the float valve to "close" and not admit fuel to the bowl.

Renners, I have heard that too. My (gravity fed) B carb does not have the slosh baffle either.
