Yeah it’s possible what I thought was an original float was already replacements

My last experience was chasing hair line cracks in the brass on several floats trying to find a good set, eventually had to give up as every carb float had one tank leaking
I did make a good float by swapping tanks but that heats up solder quite a bit and old solder hates getting melted without being replaced
Maybe that home fixed float will now last a new lifetime but I had to go back into my carburetor a few too many times for it now so I’m biased

The Napa float felt like a premium part to me however, seemed very well constructed but time will tell.

Also non of the floats I’m dealing with were ever USA made, my trucks are all Canadian and would have much larger temperature swings for half the year when it’s snow season
Many variables at play
