Carb Gasket

Just pulled the boat out of storage. Started installing the carb I rebuilt over the winter. 4160. My question is there is a paper thin gasket for under the aluminum spacer and two for between the spacer and the carb. One is about .020 and the other is a very rough gasket about 3/8 thick with plastic inserts in the bolt holes. I don't remember taking that kind of gasket out last winter. Any thoughts?

One gasket for each side of the spacer. I like the thickest gasket I can get. Seem to be less likely to have a leak from it. Two gaskets are a guaranteed leak at some point, if not right away.

The one gasket for the top of the spacer is 3/8 thick and the finish on it is so rough I would think by using it I would have a leak for sure. I will try to get a pic.

Could be you got a lousy gasket. Should be pretty smooth. Was this from a Holley Marine Kit?

Pics of gaskets, Like I said I don't remember cleaning off the thicker of the two. Would it be ok to just use the thin gaskets.

I also rebuilt my carb over the winter with the holley kit but I did not get the thick gasket. I only got one of the gaskets with the numbers printed on it like you have in the picture. My understanding is I need two of those...one for each side of the metal spacer. I have some felpro gasket paper so I will just trace the existing gasket and cut it out to make the second gasket.

I happen to have a Holley 703-47 Marine Renew Kit sitting next to me. It has two of the nice fiber gaskets in it. There is no larger gasket with plastic inserts. I don't recall having those in a marine kit before, but I don't always pay too much attention to them when I put them on.

What part number kit do you have?

I would use the thinner gaskets. There are multiple applications per part number. You could give the guys at Holley Tech and ask them why the three gaskets. In my experience, they are all good guys and full of information. 270 781-9741
