Sticking float valve

[29FordGuy]

Twice now my float valve has stuck open and when I turn on the gas it pours out the carborator intake. It is usually after sitting for awhile and no, I do not run the carborator dry when I park it. I did do that the first time it stuck so now do not. As I remember I have a pin seat float valve. Is the two ball gross jet style better and less prone to sticking? Thanks for help.

The gross style is better but even it will fail if you have debris in the gas tank. I have used them all and still prefer the Viton tipped float valves. Now I know everyone will chime in about ethanol but I have used the same one for the last 3 years with no troubles. The new valves are specifically made to account for the ethanol fuels.
