Rebuilding Weber Carbs

My fuel delivery will be provided by dual Weber 44 IDF carburetors - they came with the car when I purchased it 15 years ago, but have never been a good fit for the engine. However, I anticipate that they'll be a great fit for it now!

Many moons ago, before having a wife, a family, or even a real job, I remember taking these carbs apart and cleaning them on the kitchen table of my small apartment. Now it's time to actually rebuild them, replace the float needles, gaskets, o-rings and so-on.

For actual steps on how to rebuild Weber IDF carbs, I've found these 2 sites useful: Mark Petry's procedure and John Connolly's procedure.

 

Here's a shot of all the parts after a laborious cleaning with a nice set of little bottle brushes and a toothbrush.

For no other reason than "I could", I polished the insides of the main venturies. Will it actually help air flow into the engine? Only time will tell if every little bit helps!

One thing I did, was verify that the main jets were seating properly in the carbs. After my first inspection, only 2 of the 4 were correct. So, I "machined" them with my drill until they met my satisfaction.

 

Now that the carbs are rebuilt, it's time to work on the throttle linkage.
