Gaskets for Weber carbs to intake man.

[awdbandito]

I'm trying to figure out which gaskets I need that go between Weber IDA carbs and the intake runners. It looks like there are 6 gaskets total.
This is on a 2.7L with 40mm webers.
I see several different parts in the parts list and want to make sure I order the correct part.

Thanks,

I'd think you need the second one on the list

These gaskets are somewhat "standard" regardless of carb size. Here's another reference to prove that. Not trying to take away business from Pelican. Just pointing out that a Weber parts supplier (PMO, which is the same place Pelican gets a lot of their stuff) offers only one gasket size as well

Kevin is correct, and I'd add that you need an insulator kit if you don't already have one. This goes between the manifolds and the heads.

Steve, I believe I have insulators.
They are black and about a half inch thick and go between the head and manifolds.
I have been chasing a problem of backfiring and some spitting back up through the carbs.
I got the backfiring issue resolved by replacing all of my exhaust gaskets but am still spitting through the carbs.
I pulled the carbs and the gaskets that were used beteween the carb/manifold are home cut, and in some cases were doubled up. I am hoping this might be part of my problem.

I have Webers on my SC and looking for the gaskets above and below the PMO insulators. Still not sure I'm looking at the correct one

Is the part # 901-108-391-04?
Is it qty 12 of the same gasket?

Thanks for the help
