Plastic or brass float is the preferred way to go, but if you keep the cork, you can't use varnish, has to be shellac. Even shellac won't last forever, maybe 10-15 years with 10% EtOH in gas, but varnish probably won't last 8 hours. If I had mine to do again, I'd switch to a plastic or brass float, and as long as you have it apart, I'd check the float drop. The 34 Eights and Super Eights used a different tank and sender from the prior models and I don't recall which measurement I used, but you should be able to tell by measuring the depth of the tank directly below the float, the bottom of the float should be just a small fraction of an inch above the tip of the uptake tube.

I understand Por-15 will stand up to modern gasoline and is used to coat cork floats in early style carburetors. As I understand it the cork is dipped and allowed to dry. The stuff is very stubborn and won't come off of hands with any solvent I am aware of; I am sure Mal will attest to this.

Quote: definitely wear gloves if using POR-15 and as it says on the can "only time will remove it". There is a POR-15 solvent but it's very strong and contact with skin is not recommended, I know!
