How To Fix A Leaking Carburetor On Snowblowers, Lawnmowers...

by HIPA Jeremy 19 Oct 2022 0 Comments

This blog provides a common step-by-step instruction for replacing the carburetor float bowl gasket on yard machines, lawn mowers, snow blowers, tillers and log splitters. And here we will take a CRAFTSMAN snowblower for example.

Safety First

Make sure the engine has cooled and the ignition key has been removed.

How To

Step 1: Carefully tip the snowblower forward to make it rest on the auger housing. Detach the choke lever extension. Then use a 3/8 inch socket to unthread the three mounting screws securing the lower shroud and lift it off.
Step 2: Release the primer hose from the carburetor. You can use locking pliers to crimp the fuel line then release the retaining clamp to detach the line from the carburetor.
Step 3: Use a 10 millimeter socket to unthread the nuts securing the air intake housing, detach the primer hose from the retaining bracket as well as the breather tube from the valve cover. Then lift off the housing and set it aside, slide off the carburetor inlet gasket and detach the throttle spring and linkage from the carb.
Step 4: Now you can slide the carburetor off from the mounting posts and use a 10 millimeter wrench to unthread the mounting bolts securing the float bowl. Remove the bowl and lift out the old gasket if still intact.
Step 5: Install the new float bowl gasket by positioning it in the groove in the carburetor. Replace the float bowl and rethread the mounting bot to secure. You need to confirm that the carburetor outlet gasket is intact, then slide the carburetor onto the mounting posts and reattach the throttle spring and linkage.
Step 6: Realign the inlet gasket or install a new one. Reposition the air intake housing and attach the breather tube to the valve cover. Secure the primer hose in the retaining bracket and rethread the nuts to hold the housing.
Step 7: Reattach the fuel line to the carburetor and secure it with the retaining clamp. Remove the locking plier and reattach the primer hose to the carburetor. Replace the lower shroud by first inserting the tabs into the slot in the frame and position the shroud to rethread the mounting screws.
Step 8: Reinstall the choke lever extension with the support tabs facing up. Return the snowblower to its upright position with the repair completed. And do not forget to reinsert the ignition key.
Now your snowblower should be ready for use.
