48 IDA's do not have the ability to balance the two throats on the same carb.

They were never intended as street carbs. They were intended for racing.

I don't think that they have the accuracy in machining to put the throttle positions in exactly the same position.

The throttle shafts themselves are also made out of soft brass, so they are very easy to twist. You can do that by attempting to adjust the throttle on both ends at the same time.

Bad linkage will also twist them.

All you are going to do is twist the throttle shafts.

Weber linkage has to be light enough to blow away in the wind. You can't use all the extra throttle return springs on them like Holley set ups use.

Additional throttle return springs (as required by racing sanctioning bodies) can not go to the carbs. They have to go on the linkages.


48ida's are not for everyone. They require delicacy and patience.

Someone who is an "expert" with a Holley is just a bull in a china shop with a 48ida.

Generally speaking, you don't see IDA's on street Ferrari's.


MOST if not all people are much better off with an EFI throttle body. Those are much easier to understand.

There are little, subtle things on ida's. You won't even know that until you wreck a few sets first.
