Holley 4160 Needle and Seat Assembly
 

Just purchased an AED pro series rebuild kit for my Holley 3310-4 that I am currently in the process of putting back together. This is my first carburetor rebuild. Does this look right?

The old gaskets were paper, but it looks like the AED kit has mostly nylon gaskets (no complaint here). The fuel bowl sight plug gasket is more like a copper ring gasket.

Looks good. I'll take nylon vs. paper any day.

Cool, thanks.

The pro series rebuild kit comes with shiny new fuel bowl bolts too. I would recommend it (about $45). The only thing I've noticed missing so far is the idle mixture adjusting screw gaskets (which came with the new primary metering block anyways).
