If your equipment does not start or has running issues after it has been sitting for more than a month the problem is often related to deteriorated fuel.  Gasoline from the pump will start to deteriorate in as little as 30 days and can cause varnish deposits in your fuel system.  Fuel stabilizers will help prolong the fuels life but there is still a very good chance that you will have problems.  Also draining or siphoning out your tank is not helping your there is still fuel in the carburetor and fuel lines.


Please fallow these steps when storing your equipment to help avoid fuel related problems.

  1. All fuel used in your equipment should have an octane rating of 87 or higher (93 octane for 2 cycle) and contain no more than 10% ethanol.
  2. Purchase only the amount of gasoline that will be used within 30 days.  Add fuel stabilizer to the fuel the day you buy it, this will help keep the gasoline fresh for up to 90 days.  If the fuel doesn't get used up it is good practice to dump the remaining fuel into your car and start the process over again.
  3. When storing equipment for 30 or more days it's a good idea to run the piece of equipment dry and try to get all remaining fuel out of the tank, lines and carburetor.   Add some ethanol free fuel to the tank and run the piece of equipment again for several minutes.  By doing this you are flushing any remaining pump fuel out of the system.  It is best to leave the ethanol free fuel in the system to keep the gaskets from drying out.
  4. Do not top the tank off with fuel from the pump as this will ruin all your work.  Your goal is the minimize or ideally eliminate the pump fuel remaining in the system. 
  5. Best case scenario is to run ethanol free fuel all the time. ​  We mostly recommend this with 2 cycle equipment since they will only go through a gallon or two of fuel a year.
  6. As usual feel free to call us with any questions or concerns.

The vast majority of equipment we see come in for service at the beginning of each season are for fuel related problems.  Ethanol is the number one culprit for these problems.  


What happens is, since gas at the pump contains 10% ethanol and ethanol is hygroscopic which means it absorbs water.  Ethanol will absorb water out of the atmosphere causing water to build up in the fuel system.  Ethanol is also a very good but bad solvent causing problems with gaskets, float needle and seats, diaphragms etc.
