What causes a brass carb float to colapse?

Sounds like the float-bowl vent may have gotten plugged. Or maybe water got in the carb and froze at some time.
Or possibly, some ***hole removed the float, stomped it and put it back in the carb just to mess with your head..I'd be lookin at Ryan.........

 

Your local NAPA might have a float or 2 in stock.
I think they collapse when they have pressure blowing through them, but why would someone turbo or supercharge a little 2 bbl?

 

Kevin,
This guy is in Olathe, he sells on Epay and you may contact him and see if you can get a better deal if you pick it up.

Or you could call this guy, I know his cousin.

Carbs with br*** floats should NEVER be used on planets with higher atmospheric pressure than ours.

Suppose that rules out underwater applications too then.

Factory floats are certified to a depth of 20 feet MAX.
Or course,if you car is in more than 20 feet of water you have other problems.

 

Br*** floats dont like blow through mcCulloch supercharger setups very much.
Dont ask me how I know...

 

if it's not too crushed drop it in boiling water

it'll pop out

drill a small hole

let it cool

use a soldering iron to close it up..

maybe it had a leak in the past and someone used too much heat sealing it back up?

 

Oh yea, here is another site that I saved also....

Metalshapes is right on, if you run a paxton, mccolloch or kaiser blower on a blowthrough system with any decent ammount of pressure, it will most likely crush the floats on old carbs, this isn't as big of a problem with new ones...

 

Age causes them to collapse. Much like it has me.
Grim,
If you want I'll run by the NAPA down here and see what they want for a float. We can run it through the Friendly Auto account and git a deeeeal.
