But this is shade-tree engineering at its best :lol: and equally likely to degrade instead of improving performance. However, it will be different. And if it runs like crap, at least you'll know the mid-range didn't need richening.
Meanwhile, the EPA ancestors will be rolling in their graves. :laugh:
Good Luck!
Edit -- posted before seeing otakar's
intervening post, which seems a very
reasonable no-nonsense alternative.

As an experiment, it should do no harm to put a small thin washer underneath each jet needle clip to slightly raise its position and thereby enrichen the mid-range.

There is nothing "shade tree" about shimming. That is SOP on a non adjustable needle. The problem is getting "shims" not washers. The positioning must be exactly the same on all four carburetors with in .003" Otherwise you will learn the true meaning of the word miss-synchronization. You have to know also how much to shim. Shimming would be one of the things I would do to his stock needles.

FYI, I had to tweak the needles on mine and those needles have five slots which are all about .030" apart. I found some small (#4 maybe?) steel washers for shimming that are about .015" thick which is a half slot each. A change of .030" (full slot) is a pretty big change on mine, you might try .015" increments. YMMVAs an experiment, it should do no harm to put a small thin washer underneath each jet needle clip to slightly raise its position and thereby enrichen the mid-range.
As stated above: use a caliper to measure the thickness of the washers and make sure they are all the same to avoid getting them out of sync.
