I have had good luck with the plain brown Holley gaskets. No swelling and slimy blue stuff. We use a hole punch and enlarge the holes where the booster pulls through the gasket. the gasoline gaskets have a much smaller hole than is required for flow.

Braswell has graphite coated gaskets that I believe are the best out there.

The ones you really DONT want to use with pump gas that contains ethanol are the red colored non stick ones. I've had good luck with the green or the stock black ones.

Mark, are the braswell gaskets thicker than a standard gasket? I got some red orange colored gaskets from quick fuel that had similar print on them and they were a touch thicker. They did seem to work really well also, but I haven't used them with methanol only gas. Most of my carbs have come back from Ruepert with plain brown gaskets, I haven't had any issues so that's why I recommended them.

Interface Solutions makes several different gasket materials. BLP and Quick Fuel used a different one that is a good gasket, one coated the other not. Reinz has some decent material they both used later, BLP is still using. But so far I've found nothing better than the Braswell.

Will take that advice next time I order gaskets. Thanks.
