Weber 38 for VAIRBUG manifold adapter
Posted by: corvairbusguy ()

Hi, I'm having a tough time finding a manifold adapter to fit a progressive weber on my spider manifold. Somebody got one or do I need to hire a machine shop to fabricate one for me?

ps, Ive been speaking to the salesguy at Redline. The weber dimensions are 1-3/4 by 3-3/8 and the holley pattern manifold is 5-1/4 by 3-1/2

Are you looking for an adapter to bolt the Weber to a turbo?

I think his "Spider" manifold is just a center mount carb manifold

Individual carbs on the heads is better for city driving than the centermounts.

It would be helpful if these vendors would provide the exact dimensions of the bolt patterns

What size Holley are you running? Plenty of guys have good luck with a 390cfm Holley.

take the choke completely out and drive it like a buggy cool smiley , re jet ? check your plugs first. you need exhaust analyzer to get the jetting right.

That big hesitation off of idle is because of where the carb is located. lots of topics here regarding center mount carb drivability.

Rod suggested removing the choke flap but idk....

I took it apart and cleaned what I could BUT the metering block would not budge. Must have been glued on so rejetting is on hold.

list # is where?
