There's an SAIB on the MS carburetors calling for replacement of the white internal floats with metal or solid plastic. The carb data plate should have had an "M" stamped on the data plate if the plastic white float was replaced with metal...(should have a "V" stamped as well for the single piece venturi as well). A leaky, sunk float would cause the carb to go to a over-rich situation causing it to stop from idle..a full throttle may have helped, carb heat normally adds more air and may have…

It's amazing Precision Airmotive and I'll bet Tempest is still using white plastic floats.

<p>Geoff has an interesting point - carb heat. The corvair, when modified into a flight engine, has a carb that is not bolted to the warm oil pan. It is on the end of an intake tract, not attached to the warm mass of the engine. This is just the same as small Continental engines and Franklins. They all need carb heat anytime the power is pulled back, unless you have a carb temp gage and watch it carefully. I am not saying for sure that was the problem, but it certainly could…</p>
