How to Troubleshoot Hard-Starting Toro Snowblowers

Turn on the Toro snowblower, and allow any old gas that may have been left over from a previous season to burn off. Then, fill the fuel tank back up with fresh fuel once you are done. This may fix the problem with hard starting.

Check the Toro snowblower's carburetor if hard-starting problems continue after troubleshooting the fuel tank. The carburetor bowl can be found about halfway up the right side of the engine block. Observe it, and see whether it is leaking.

Tighten the nut on the underside of the Toro snowblower's carburetor bowl if the carburetor is leaking. Use a socket wrench to accomplish this.

Drain the carburetor bowl entirely if problems persist. Position a pan under the carburetor bowl, and then loosen and remove the nut on the underside of the bowl entirely with your socket wrench.

Wait as the fuel and liquid fully drain from the bowl into the pan.

Set the nut back into place on the underside of the Toro's carburetor, and then tighten it into place with your socket wrench.
