Carburetors are dumb

So even though your carb was designed to work on a 352 or probably 390, you might be able to trick it into working on your 302. I don't know, maybe I'm the dumb one; but those jets seem very big for any engine. Example, my 4100 1.12 has 48 primaries and 57 secondaries. If your up in the hills with the music, you'd probably want to drop that further to 47/55 or something like that.

Problem is though - Old Ford jets are hard to find even over here; won't be any easier in Austria. Ebay?

Check the power valve too. I think 6.5 was pretty standard.

Also, check the FE forum - lots of 4100 guys over there.

OR - easiest yet, find a different carb.
