That makes sense - front to back will change with tilt but the center won't. Thanks.The fuel level is checked at the center of the bowl whether installed or not.

With my bike sitting on its tires on a level concrete floor the difference between 0º (or verticle level) to the carb bowl upward pitch/angle measurement shows 9.80º .Anybody know what the tilt angle is for stock carbs on a Commando?
You took the words right out of my mouth. Marvel Schebler said the same thing about their foam floats. [ie They are "sink proof"] They have since been removed, due to aircraft falling out of the sky! The truth will out, in due time. I'll stick with the plastic floats.They said that about the Titanic

and when sat upon it is very close to level?

I hope that a bike did not change level by 10 degrees by just having a rider sit on it.
After you soak it in boiling water or heat it with a torch, and you'd better have calipers handy to measure how much it moved....The correct parallel pin punch and a toffee hammer will do it easily
I use a hot air gun ,heat is your friend hereAfter you soak it in boiling water or heat it with a torch, and you'd better have calipers handy to measure how much it moved....
I've done it, but it ain't fun.
Mike, You are correct about foam floats being cheaper to make. I'm planning on Amal Premiers for my Mk III project. However, I'm going to save my old plastic floats and matching float bowls, for when those foam floats sink. Lots of issues with foam floats on Lycoming, Continental and Rotax aircraft engines. Linked below is a thread about sinking Rotax floats. It's 24 pages long!Yep, the introduction of foam floats was about saving money, not about making a better float. They are punched out of a piece of foam; plastic or brass floats are FAR more difficult/expensive to produce. I ASSUME (a dangerous assumption) that a current foam float is superior to the older versions but I don't know that to be the case. Quadrajet foam floats were well known to absorb fuel over a couple of years though they could make it through the warranty period, which is the ONLY thing that matters in most mass-production applications.
I can't claim to have a lot of experience with a multitude of AMAL floats but I never had a plastic one fail and the originals in my 1973 carbs (replaced by premiers in '18) are in perfect operating condition. I do have a lot of experience with foam floats on auto carbs and none of it is favorable.

Does anyone know what the weight is of the new foam floats?
Yea, bugger all when immersed in petrol, surprise surprise they float!Mike, You are correct about foam floats being cheaper to make. I'm planning on Amal Premiers for my Mk III project.

I doubt they have floats on Cessna. What happens when the plane flies upside down. They do you know. They have very large and very special chainsaw carbs [ as an example ]. They work at any angle. They use a diaphragm instead of a float. Any dumb shit ought to know that. Come on. Please don't make uneducated guesses or presumptions. It spoils the forum for those who are not that mechanically minded."
Don't be surprised when Amal switches away from foam floats in a decade.
A sinking float on a Norton is nowhere as thrilling as on a Cessna."
I'll bet that's TRUE!!!
Thanks for the insult. I'm not the one who doesn't know what he's talking about. FYI, most piston aircraft engines which are not fuel injected [including Cessnas] use a single barrel, updraft carburetor WITH a float.I doubt they have floats on Cessna.
