How to Rebuild a Carburetor for a Troy-Bilt Tiller

Turn off the Troy-Bilt tiller.

Locate the Troy-Bilt tiller's muffler. This can be seen near the bottom left of the Briggs & Stratton engine assembly. Remove the bolts holding the muffler against the engine assembly by loosening them with your socket wrench. Set them aside carefully, as all bolts from the engine will need to be reused.

Take the dipstick out of the gas tank. Look along the tank for the bolts that hold it in place. Remove these bolts with your socket wrench, then pull the tank away from the rest of the Troy-Bilt tiller, taking care not to spill any fuel.

Look for the distinctively shaped Troy-Bilt tiller carburetor bowl about midway down the right side of the Briggs & Stratton engine assembly. Disconnect the attached carburetor intake with its air filter from the back of the bowl by removing its securing bolts and screws. Remove the bolts with your socket wrench and unscrew the screws with a Phillips screwdriver.

Position a pan beneath the Troy-Bilt tiller's carburetor. Loosen and remove the lone nut on the bowl's underside. Liquid will spill into your pan. Allow all the liquid to drain.

Slide the now loosened carburetor bowl completely off the Troy-Bilt tiller. If there have been noted problems with the carburetor that require a switch out of parts, have your replacement carburetor bowl ready. If not, take a moment to clean out the existing carburetor bowl with some carburetor cleaning solution and a rag.

Slide and twist the carburetor bowl back into place on the tiller's Briggs & Stratton engine assembly. Secure it by reinserting and tightening the single nut into the bottom of the bowl with your wrench.

Refasten the carburetor air intake and air filter to the back of the Troy-Bilt's carburetor bowl by reinserting the bolts and screws with the socket wrench and Phillips screwdriver.

Position the gas tank back onto the Troy-Bilt tiller and secure it in place by reinserting its bolts with the socket wrench.

Reattach the muffler in the same fashion as you did the tiller's fuel tank.
