I just removed this NH from the '14 and swapped it out with a rebuilt one. This one looks pretty good & possibly can be just cleaned up and reassembled with new gaskets, float valve and such other parts as disassembly might reveal. One oddity - there are two magnets on the outside of the float bowl. Any ideas why they were fitted?

A fail safe device (just-in-case the potato filter screen didn't do its job or has a hole in it) to prevent rust particles for the owners seasoned gas tank from clogging the carburetor .

That was my thought too. Still, there might be other explanations. Some folks believe that a clothes pin on a fuel line will prevent vapor lock or swinging a dead cat in a graveyard at midnight will . . .

Running fuel thru a magnetic field re-aligns the molecules for higher octane & fuel economy. At least thats what one JC Whitney product claimed.
Maybe those magnets are why that 14 runs so well.

Gasoline is not magnetic. If those "magnets" were able to attract/realign the molecules of the gasoline wouldn't those molecules stick to the walls of the bowl or fuel line where the magnets were located and clogging things up?

My mechanic put a magnetic fuel filter on my 67 Skylark. I had run out of gas and borrowed a metal gas can to get it going. Evidently the can had an abundance of rust that took residence in my fuel tank. Rust flakes would get in the carb and flood. The little magnet in the fuel line solved the problem without removing the gas tank which would have been an issue since someone had welded an angle iron trailer hitch to the frame. The mechanic said he often installed the magnets back in the “old days” when gasoline had issues.

Given that rust is paramagnetic, I'm intrigued that a magnet would be expected to stop rust from migrating into the carb, though I know that many folks swear by it.

Magnets in oil filters to add an extra layer of filtration?...I can see it, particularly if the filter is routinely changed far beyond its useful range; magnets to capture rust, anywhere, not so much. If a magnet is trapping or constraining something in the fuel line and keeping the carb clean, it's working as intended, but it isn't FEO2 that it is trapping.
