Thanks everyone for the help. The float is hollow plastic. The plastic is cracked and the gas is sinking the float. Good thing is I think I may have found one here locally. The mower is 7260G. I will check that part number out on ebay. Thanks again everyone.
I'm having a hard time finding a carburetor float for 681843 carb. The float part number is 681639. Does anyone know if there is a replacement float for this carburetor? I can't find anything on ebay and lawn boy says this part number is discontinued. Thanks
