Where do I get these little plastic gaskets that are on the screws for the float bowl. Mine are leaking. What are they called so I can google them. Don't see them on Holley's website. Could there be another reason why they are leaking. Will new gaskets solve this?

They come with a carb kit. You can get them anywhere. It's the Float adjust gasket.

I think they come with a needle and seat kit.

Found it. Thanks guys. Those stupid things keep me from boating this last weekend. Motor fired right up for me. Didn't even make it off the trailer when I saw that leak.

Where does the O ring in this photo go. I didn't see one when I pulled mine apart.

The o-ring goes on the needle and seat body, Ive had them go bad before, not a bad idea to change them.

Could a bad O-ring cause an external leak? Do I have to back the float adjustment screw all the way out to change it? I am looking for an exploded view of this online and I can't find one.

I had small threads come off of my needle a seat because of my chrome bowls. They ended up going between the O-ring and the needle causing a bowls to over flow and leak externally.

Sounds like I should take the float bowls off and investigate.

No, just loosen the 5/8 nut and thread out the whole assembly, change the o-ring and re-install. Check to see that there is no debris where the needle seats in the body. A bad o-ring or stuck needle from debris will cause leaking.
