Attached are several photos of bing floats. The first is a Bing 1, 2, or 3 dot float that weighs 2.6 g. In mo-gas, the pin rides just above the surface.
The second shows the newest Bing float that weighs 3.2 g. The pin sits even with the surface.
The third shows the new Marvel Schebler float that weighs 3.8 g. The pin is submerged.
And finally, the super duper 3.2 g Bing float after several months setting in mo-gas. It now weighs 4.0 g and only deserves a poor quality photo.
Each float would be pushed further into the fluid due to the fuel pressure at the float needle, the weight of the float needle, weight of the float arm, and as shown, the weight of the float itself.
Each float height is 0.828 inches, or pin height is 0.414 inches, possibly coincident with the 10.5 mm float arm set up measurement.
The 3.2 g float sits about pin high in the fluid. That means that fully submerged, it could displace 6.4 g of fluid. For each 0.6 g increase in float weight, the float will sink another 0.08 in or 2.0 mm (0.818 in x 0.6 g/ 6.4 g).
If the float sits lower in the fluid, the fluid has to rise higher in the bowl to shut off the float needle. To return to the typical operating fluid level in the bowl, should the float arms be adjusted for the heavier floats? From the typical 10.5 mm to 12.5 mm for the super duper (soon to sink) Bing floats or 14.5 mm for the new MS floats?
