Many complaints of "hard to start", or "runs rough" are due to old gas.

Today's gas is Ethanol, which contains alcohol made from corn. This was mandated by our govenrment. A result of this stuff is that it gets old/stale quickly. It reacts with the humidity in the air (power equipment have vented gas caps, allowing air to enter)and can happen in 30 days!

​

Ways to extend this shelf life is to:

1. Add fuel stabilizer to gas cans.

2. Keep gas tanks full (limits amount of air that can enter a tank.

3. Store gas in sealed containers, and in dry locations out of the sun.
