Hello World!

Looking for recommendations on rebuilding my Weber carburetors...

Is this a DIY project for a newbie, or
Are there recommended shops or vendors here for that?
(updated with pictures)
(2 new pics added - other side of carb)

Thanks in advance,
Sean

Which model and are they vintage (made in Italy) or later?

If you're talking IDFs they are easy just record all your settings before you disassemble them and take your time setting the float heights.

A full rebuild kit comes with about 30-40 parts (mostly o-rings).

Thanks for the replies.

New on this journey, I am not at all knowledgeable about the carburetors yet.
I don't know the model, so I have added a few pictures of the carbs to the original post.

Weber and Italian made.
These are on a 2.0L 4cyl.

How do you get the orientation of the pictures to be correct? They show up fine on my computer but are upside down when added to the post?

Thank you,

Sean

Depends on your budget. If you have the money have them done professionally. Your driving experience will be much better with great carbs. I have done it myself and it’s doable. YouTube!!! If you decide to have it done I hear they come back like new if you send them to National Carburetors here in Jacksonville Florida. They are on line.

I rebuilt mine myself, the IDFs are really pretty straight forward. Then I had a professional tune and swap jets as necessary.

Those are vintage IDF made in Italy Webers.

If you just want to flush them out and put kits in them it's an easy project. There's a good youtube video on how to properly set the float level.

If the throttle shaft bearings are bad it's more complicated and you may want to hire the rebuild out. You can check them by grabbing the linkage at each end of the throttle shafts and see if they have movement (the bearings should be tight with no up/down movement in them). If the bearings are bad there's a chance the throttle plates are also worn.

Regards,

Tim

You can find the Weber factory service manuals here:

And a lot of other useful info.

easy to do, the rebuild kits have instructions, the most important thing is to thoroughly clean

Might want to check with ThePaintedMan, George. He's in St. Pete. Don't know if he is still doing rebuilds, but here is an old thread: http://www.914world.com/bbs2/index.php?showtopic=228153

Not too hard ,make sure you use good tools so you don't chew out the jets and round off bolts,if you are unsure about assembly only do one carb @ a time ,don't take too long to do it otherwise you tend to forget where things go ,take lots of pics also.
Order genuine Weber kits as they have parts that fit properly,some aftermarket ones leave a bit to be desired,order the kits ahead of time, clean them really well before assembly.
Lots of info online to set them up so no issue there,do all your primary settings before you refit them as saves constantly removing them to solve issues ,you will need to do the following;
check float levels,
set throttle stops,
check enrichment lever adjustment,put fuel in the bowls ,check for leaks and test accelerator jets for clean even spray down the throats,
set mixture screws to 2.5 turns out .
Good luck .

Easy to rebuild.
Take apart and soak in carb cleaner overnight.
Make sure you don't soak any plastic parts in the cleaner.
Reassembling is easy but tuning is a bit of a pain.

Thank you All! This information has been very helpful. Especially the link to the manuals.

Next question:
Is there a preferred vendor or brand for the rebuild kits? I want to get a good quality kit.

Thanks again!

Hello,

I took a couple new pics and put them in the original post.
There is a clear 44 stamped on the side but also looks like a 39 stamped.
So, are these 44s?
Should I look to get a jetting kit too? Or, wait on that to see how they run once the rebuild is done?
Car didn't / doesn't run well now but it's a lot of things.

With the great advice I'm looking to tackle this myself and now source the correct rebuild kits.

Thank you,

Sean

I pulled off the very dirty air filter this is what one looks like. Was expecting to find velocity stacks but didn’t on either carb. Look down one of the barrels and can see some RTV poking out.

Should there be inlet venturies?
If so, where do I get replacements? What do I need?

Thanks!

Posted by: Mark Henry Mar 25 2019, 06:57 PM

Yes they're 44's, really meant for 2270cc+ engines but will work on a 2.0.

I'd machine the air cleaner bottoms flat and add velocity stacks. I think that's what you're calling inlet venturis.

You also need a sync tool, I recommend the more expensive BK snail sync or the china copy, don't bother with the uni-sync.

You need a good linkage, #1 reason for tuning issues is junk linkage. I hate the hex bar linkage and have tossed many sets in the trash.

A wide band O2 meter and a jet reamer set makes jetting easy.

I use 3 fuel filters, one before the pump and one before each carb.
Use FI hose clamps not the common worm gear clamps and use a quality menthol proof fuel hose.
Fuel pump must push no more than 4psi, 3.5 would be perfect, I use a pressure regulator.
