Never, never, never assume a cork float in a LawnBoy carb. is OK. After completely redoing a nice LawnBoy mower, new seals, new reed, new paint, the darn carb started flooding and leaking, all over my new paint, yuck.

I put it in a pail of gasoline and it sank like a stone. I then tried out a couple others I had hanging around and they did float, exchanged the float and the carb is doing fine now.

Always test your float. Put some gas in a small bowl and see if it floats. The end with the metal end will be below level, thats OK.

The old Lawn-Boy Cork floats can be replaced with modern Plastic floats.. I don't remember the part number, But it's a replacement for a TORO "R-Tek" (Duraforce) Snow Blower float.. I've done it to a couple of machines and it worked great..

Yeah, it would definitely be better to have a plastic float instead of a cork one. Somehow, I can't see cork being an ideal material for a fuel system component.

Hi! Cork floats have been used for a long time but they do have their limitations. The coating can wear out, especially if you clean the float with carb cleaner a lot or soak it in cleaner. Floats are not that expensive at about $10.00. Bill
