Carburetor leaking fuel!!!

The rebuild kit will come with a couple of different N/S combinations. It will also have all your gaskets. On my Holley, two of the needle and seats looked like they were an exact match. One was .110 and the other was .097, but the instruction sheet that came with the kit indicated that the .110 was the correct match for a needle and seat marked with an “H” on it (which my needle and seat did). Here's a tip: Put a dab of Vaseline on the black O-ring; it makes the job way easier.

Is there a specific rebuild kit that I need to order? Again, Summit Racing has lots of kits. My carburetor is a Holley Street Avenger series, p/n 0-83770.

I'd say it is a .110 needle and seat.

And this would be the whole kit you need:

Roll onto service parts, then down to 37-935:

Why Vaseline and not just grease or a dab of oil? Is this to lubricate the new O-ring such that it slides easier into the chamber of the fuel bowl during installation?

Yes, lube up the O-ring so that it slides in and sits nicely. There's probably better lubricants, but I've used Vaseline on them since I was a young teenager (and I'm now in my 60's). It's never let me down yet.

I used vaseline on a rubber once now they call me dad.I would be very careful using it again . By the way you know what they call men how use the withdrawal method? DADS!
