Cork Float

[Edwin Howard]

I have heard something about coating a cork float in a glue of some sort. Is this a real thing, and is it necessary?

If your float is in good shape, as in not crumbly then you probably don’t need to do anything. Tubs has a long term experiment going showing no difference in a coated, vs uncoated float. Maybe he will post it again.

some use  what is called “airplane dope”… a  clear varnish for model planes which is fuel proof.   Hobby shops sell it..sometimes.

i have used medium thick crazy glue brushed on fast  after a light sanding of crums.     careful  with crazy glue fumes in eyes, nose etc…

apply in well ventilated area.

some  cheap amazon carb kits  come with floats.

the kits have bad reputation  but the floats work 🙂   (gaskets known to melt… inlet needle seats  threads don’t work to good.  the rest i ok

I started this almost 9 years ago. I can’t see where the little cork has lost any of its buoyancy. The old cork, that looked to be varnished, dropped some the first year but has stayed the same after that. Its got a pretty good sized wood screw in it pulling it down.

Thank you all for the information! Does it matter the type of cork used? The new one I have appears to be made of little bits of cork that have been glued tightly together, kind of like osb. I weighed it with a solid cork of the same size, and they were almost the same. I just wonder if the gas will break apart the chunks of cork or if it is safe to use.

Yes. What you have is pieces of cork glued together. You don’t want to use that. Try hardware stores and home improvement store’s. They have corks. You can tell if what they have is what you want just by looking at them.
