Troubleshooting your Husqvarna front-tine tiller when its engine runs rough or misfires

If your tiller engine isn't running smoothly, cleaning or replacing the carburetor, tuning up the engine or replacing bad gas may fix the problem.

If you left gas in the tank during the winter without adding fuel stabilizer, drain the tank and fill it with fresh gas. Add fuel stabilizer to gas to keep it fresh during the off-season.

Stale fuel can clog the carburetor, so clean and rebuild the carburetor if the tiller continues to run rough or misfire after replacing the gas in the fuel tank. Replace the carburetor if it's too clogged to clean.

Tune up the tiller engine by replacing the spark plug and oil. A dirty spark plug won't ignite the fuel properly. Old oil won't lubricate engine parts well so the engine idles roughly because the piston or pistons won't move smoothly through the cylinder.

How to replace the drive belt on your Husqvarna front-tine tiller

• Pull the spark plug wire straight up and off the plug.
• Wear work gloves to protect your hands.
• Remove the mounting screws that secure the drive belt cover to the tiller and pull the drive belt cover off.
• Remove the bolts from the belt keeper behind the engine pulley and pull the belt keeper off.
• Remove the bolt from the idler pulley and pull the idler pulley off.
• Pull the drive belt off of the engine and transmission pulleys.
• Position the new drive belt on the engine pulley and transmission pulley.
• Reinstall the idler pulley with the belt routed over the idler pulley and through the belt guide. Reinstall the belt keeper behind the engine pulley. Make sure that the belt is properly routed through the belt keeper.
• Position the drive belt cover on the side of the tiller and secure with the mounting screws.
• Reconnect the spark plug wire to the spark plug and check for proper tiller operation.
