My 77 F-150 351M 2WD auto sat for most of the winter. When I fired it up this spring gas came up throught the 2 stove pipes in front of the choke butterfly. I rebuilt it setting the "new" float at 7/16" from the top edge per instructions and I just tried it again. Same problem gas coming up through the stove pipes. Should I trash the thing and get a Holley replacement or what?

Thanks Jeff

 

you mean the fuel bowl breather? If your getting fuel up there their either your float is stuck and over filling or you are overpressurizing and pushing past the float.

 

Yes I guess its the fuel bowl breather. All of the float parts are new. I even cleaned the carb body in carb cleaner. Every thing should be clean and moving freely. Could the fuel pump be putting out to much pressure?

When you rebuilt the carb, did you ensure you locked down the float anchor retainer around the needle seat? If not, the fuel will spew out like you describe.

 

Float anchor retainer? What does it look like?

Jeff

 

The retainer is a wire that clips onto the float shaft (pin that the float pivots on), and then the retainer goes around the needle seat. Most needle seats (also called fuel inlet seat) have a groove cut into the exterior of the upper part of the seat, and the retainer clips into that groove. The retainer wire sort of looks like a retainer that a person with braces uses. Hope that helps, sorry not hi-tech enough to post picture or diagram.

 

Thanks I fixed it and no more fuel leaks.
