Bolens Lawn mower leaking gas

A Bolens lawn mower leaking gas usually points to a carburetor sealing or float problem, and the first place to check is the carburetor bowl gasket on the bottom of the carburetor. If that gasket is dried out, damaged, or missing, fuel can drip straight down and look like gas leaking from bottom of lawn mower. Next, inspect the float needle, since a worn needle may not shut off fuel flow and can let the carburetor overflow. A bad carburetor gasket is another common cause of a Bolens lawn mower gas leak, followed by a cracked primer bulb that seeps fuel when pressed. If your mower leaking fuel issue is not coming from those parts, check the fuel shut-off solenoid and fuel lines for leaks, then inspect the carburetor float. A float stuck open can keep filling the bowl until gas spills out, and at that point cleaning the carburetor thoroughly may help, or you may need a carburetor rebuild or replacement.
