    Default PROS AND CONS Needle and Seats

    Bottom Feeder Needle and Seats

    Has any one used these? Seems they would be a good choice for marine engine usage.

    They will keep the fuel a little cleaner in the bowl if you get what I mean. Instead of spraying around in the bowl from the top...... does it make a difference....not really unless you need something that will let you keep the float level down a bit. (off road hill climb exc.)

    Think about it. The needle and seat isn't really the problem. The bowl is. Reguardless of how the fuel leaves the needle/seat assembly, its not in the "jet area" yet. The fuel still enter the bowls's float/holding chamber the same way reguardless of the type of needle assembly. They are a little better, but by how much? Now if you really want "clean" fuel in the bowl, you have to fix the bowl:

    Seems better flow, and less required fuel pressure would be benifiacal. The Braswell stuff is nice, and light as well.

    I have used them. The idea is to reduce aeration of the fuel in the bowl by dispensing the fuel below the fluid level, instead of over it. Seems logical, but couldn't tell you if it's a significant benefit.

    http://www.blp.com/pdf/install/BLPFloats.pdf If you look closely at the picture of the carb in this link, they have cut out the sides of the bowls and put in a big window so you can see all the fuel. The bowl on the left is all foamy, and the bowl on the right with the bottom feed shows how clear the fuel is. To me it looks like the fuel in the left bowl was in a blender first, but that's just my observation, not sayn' they fixed the demo...
