Sea Foam Official video: Tips for your lawn mower

Check out the following quick tips on how easy it is for anyone to use Sea Foam Motor Treatment and Sea Foam Spray to help ensure that our lawn mowers start fast, run smooth, and always have plenty of power to get the job done!


Lawn Mower Tip #1  Add Sea Foam to every fresh tank of fuel

Unprotected gasoline degrades quickly and ice augers often go several weeks without use.  By adding Sea Foam to every tank of new fuel you can eliminate the most common lawn mower problems:

  1. HARD STARTS: Sea Foam helps engines start fast by holding a fuel’s flashpoint.  Sea Foam helps to protect fuel from evaporation and the loss of light ignition vapors.
  2. HESITATION/LOSS of POWER: Sea Foam helps keep your engines running clean & smooth by preventing or dissolving the formation of gum and varnish residues that restrict fuel flow.
  3. WEAR and CORROSION: Sea Foam is always protecting engine parts from wear and corrosion by adding petroleum lubricity to the entire fuel system.


Lawn Mower Tip #2   How to overcome a gummed-up carburetor

Fresh fuel with Sea Foam Motor Treatment is the key! It only takes a few weeks for ignition vapors to evaporate and for gum and varnish to form in fuel.  Whether your mower is a 2- or  4-stroke, almost every gas mower has a carburetor intake. Carburetors are vented to the atmosphere so they’re particularly prone to sticky fuel gums.

If your engine won’t start or runs rough, try this or go to our HOW 2 Instructions menu:

  1. pour out or siphon the old fuel from the tank, then remove the air cleaner and use your primer bulb to clear the fuel from the carburetor
  2. add a cleaning dosage of Sea Foam to the empty tank followed by a small amount of fresh fuel
  3. with Sea Foam mixed in the tank fuel, press your primer bulb 3 or 4 times to draw the fresh fuel and Sea Foam into the carburetor
  4. then let the engine sit overnight  to allow the Sea Foam to dissolve any fuel residues from the carburetor (Older or excessive gum can require a longer – Partly because Sea Foam is harmless, soak as long as needed to dissolve stubborn gum formations.)

Once the engine starts, the Sea Foam in the fuel will continue to clean and help restore lost engine performance.


Lawn Mower Tip #3  Engine Storage

When ready to put away your mower for several months:

  1. add Sea Foam to the tank to stabilize the fuel, then run the engine long enough for the Sea Foam to work through the carburetor (3 minutes for a push mower, 5 for larger)
  2. with air cleaner removed and engine running, spray a series of 4 or 5 bursts of Sea Foam Spray into the carburetor throat, then a final fogging burst to drown out the intake
  3. remove the spark plug and spray a burst to coat the cylinder cavity 

With Sea Foam in the tank and carburetor and Sea Foam Spray in the chamber area, the entire fuel system is protected and lubricated for long-term storage!

Always remember:  Sea Foam is made from highly refined petroleum.  It cannot harm an engine and you cannot add too much to fuel.  In fact, the more Sea Foam you add to fuel, the better it cleans and protects!
