1. OLD FUEL- old fuel left in the tank is the major source of particle build-up causing clogging, tarnishing and corrosion of the carburetor and fuel system. Today's fuel contains ethanol which draws moisture from the air.  Since water is heavier than fuel, it will sit in the bottom of the fuel tank.  See pictures on our "Equipment Wall of Shame".  Recommendation: Use fresh fuel every 30 days and run it out of fuel often.  

EQUIPMENT STORAGE-  It is extremely important to drain the fuel or run the fuel out of the tank and fuel system after the last use to prevent condensation build-up & rust.  Approximately 20% of machines have fuel shut off valves or switches. To run the gas out of the carburetor and fuel system, turn this this switch to the OFF position while the equipment is running and let the engine come to a stop.  Leave the shut-off switch in the off position and store for the season. This method is the BEST way to extend the life of your equipment.

Always try to store equipment where there will not be any freezing and thawing. Otherwise, condensation build-up will occur and corrosion will follow.  Storing equipment with fuel stabilizer in it is not recommended for long periods of time.  If it is not diluted with a full tank of gas and shaken to mix it before starting the following season, it can cause more harm than good.  Also, never use dry gas with fuel containing ethanol. Dry gas contains alcohol which causes the ethanol to absorb even more water than if it wasn't originally used.

2. BATTERY FAILURE- The life span of a riding mower battery is about four years. As it ages, it may fail to hold a charge for very long. A riding mower battery should hold a charge for 3-4 weeks when the mower is not in use. An older battery that only stays charged for 1-2 weeks is likely ready to fail completely.                                                                                                                                             Recommendation: A fully charged battery at the start of each season or replacement

3. SPARK PLUGS that are worn or dirty- Wear or carbon build-up will result in start-up failure.   Recommendation: Change yearly

4. LACK OF ENGINE OIL CARE- Routinely check and change the oil-  Scheduled seasonal maintenance along with frequent oil checks will significantly prevent the most common causes of start-up failures.     Recommendation- Yearly Seasonal Tune-Ups

5. AIR FILTER CLOGGED- If your air filter is congested or clogged it won’t be able to suck enough air into the fuel system. This will cause the engine overfill with gas, restrict the air flow and trigger the engine to run rough with a loss of power.  In addition, be careful not to overfill the oil, it can get pushed through the system and saturate the air filter with oil.  See pictures on our "Equipment Wall of Shame" page.  Recommendation: Clean the air filter out with a compressor or replace it each season
