I see Tempest has added lots of new stuff for the MSA/Tempest/Volare carbs here:

Great, now the "new" foam floats have a SB against them? Lovely lovely lovely... Glad I didn't jump on the bandwagon on that one. Happy with my brass float here

Guys: Has anyone determined/heard if the new foam floats are ethanol tolerant? Dan

Well since "certain additives' are causing problems with them, I'd guess NO! Go brass or go home. I suppose the epoxy is a solution if it's resistant to everything.

I love my brass float... they can kiss ^#@...

Did you guys read the data on that page?

The new float is not having problems, the old foam ones had problems.

Here is Volare's verbage on what this newer float is made of:

"3. Background: Foam floats may deteriorate in certain fuels and fuel additives. Brass floats, regardless of manufacturer, may crack, leak, corrode, and/or mechanically fail. White plastic hollow floats may leak. Deteriorated, leaking, or broken floats can negatively affect engine performance, regardless of the identity of the manufacturers of such floats. Volare and its immediate predecessor Precision Airmotive have worked arduously to address these issues by developing the first solid, blue epoxy composite float. This float is impervious to the fuels and fuel additives used in the aviation industry today. The solid, blue epoxy float is not a "foam" float. It is not a thermoplastic. It has no soldered or riveted joints. Being solid, it cannot fill with fluid and sink, even if pierced. The float is essentially chemically inert. The stainless steel bracket is cast securely into the float body and is not subject to separation in normal use. This float design has been in production for several years. It is installed in thousands of carburetors, including carburetors sold by Volare and its predecessor to current engine manufactures since its introduction. There are no known cases of failure or malfunction of this design."

For people who hate to read or have trouble with reading technical documents, here is a visual of the ones to replace or keep straight from Volare:

The "Old" foam float this year was the "new" foam float last year... SB came out, and I opted not to change it... glad I did

. The brass floats last forever almost all the time, they can scuff, and develop pinholes, but it's RARE. The main problem is people trying to solder the pinholes and blowing the darn thing up in their face because the gas fumes inside ignited.

I would not put a foam float in my carb for any reason. Brass floats work and perform well if the plane is flown and water is no a factor. I've had brass floats in my aircraft for years (20 +) with no issue. BS bulletin if you ask me.

JMHO...

Yea, its hard to imagine a brass float that has been around for over a hundred years in use in millions of engines could fail. I guess you just have to have someone close to you with a very new engine and carb almost die because one sunk to bring out the fact that they can and do fail.

I've got a Marvel Schebler carb typical of these aircraft carbs on my '49 8N Ford tractor. It also has a brass float, and I must say it looks original and functions well. The tractor has tried to kill me before, but the float wasn't the cause.

Just look at how foam deteriorates in water alone, and they want to put foam in my carb??? NOT!
