Scat intake manifold for Weber Progressive fit

It seems obvious that my intake manifold for the progressive Weber will be too tall to close the engine lid with the air cleaner installed. I've heard of cutting into the deck lid and carving out a clearance, but considering the potential for water coming in, another way around this would be to shorten the neck of the intake manifold by 1" right under the carb base. Any thoughts ? Thanks.

Clearance to carb or to air-cleaner...?

Giday, Scott. My measurements show that with the engine installed, carb and air cleaner installed, I won't be able to close the deck lid. If the air cleaner was about 1" shorter, I'd likely be ok. One
solution I see is to cut (then take out about 1")and reweld the tallish neck of the intake manifold but I'm up for suggestions.

Depending on existing carb/filter assembly size, a shorter air cleaner might do the trick. K&N make some assemblies that are 1-1/2 to 1-3/4 inches tall. Post the Weber model number here-there are others that may have faced a similar problem.

What about a remote air cleaner, like on a Karmann Ghia?

All you need is one of these:

It will drop the air filter element an inch lower around the carb.

The carb is a Weber 32/36 DFAV. I had no idea there was such a variety of filter applications. The simple solution will be to just install a shorter filter element. It doesn't look like that drop down adapter would clear the choke and accelerator pump bits on the carb anyway.

Cut out a section of the rain shield about 1" larger than filter move it up and fiberglass the sides. I would not alter the intake or even use a short filter - both alter flow or air/gas mixture.

I don't have quite enough distance to raise the lid, Wolfgang. I need about a full inch and I can only raise a cutout 7/8" less the thickness of the glass without carving into the grille. I'll have the engine in place next week and only then will I have exact measurements and then fix a cure. I like your idea though.

If you have a good fab shop they can make the part to fit your car
i am lost as to why you have not gone this way .i have found that with an older car this is what you need to do if you need to be happy

I've got the same Weber carb, but can't say whose intake it sits on.
I have a 1-3/4" high K&N filter.
I cut away the lower half of the fiberglass "bubble" that shields the filter, then used a piece of thin aluminum flashing to close over that area; reshaping it slightly. I lapped the upper part of the aluminum about 1/2" over the remaining portion of fiberglass bubble and fixed it in pace with a little epoxy and a couple of small pop rivits.

I'd post a picture, but with the fiberglass/aluminum bubble portion painted flat black, the fix is completely unnoticable.

I followed your lead, Brian and it worked out fine. I went with a shorter air filter element. Instead of the aluminum flashing, I releived the Bride of a short rectangular cake pan,screwed it to the remaining fibreglass canopy inverted, painted it flat black and you can't even see the mod. The electric choke is as someone else mentioned...it starts up fine when cold, but the idle is low initially then the rpms go up when warmed up.

Just to add to the Weber intrigue, or is it the mystic, my Weber does EXACTLY as David said, "it starts up fine when cold, but the idle is low initially then the rpms go up when warmed up."

But then I DON"T have any choke! Aww well . . . .
