Why Does my Small Engine Run Better with the Choke on?

Unfortunately, we hear this question asked more often than ever before. Although it may have something to do with your E3 Car Spark Plug, it is more likely the result of using E10 gasoline, especially if you live in a hot, humid area of the country. Since the spark plug is the easiest place to start, take your spark plug wrench and carefully remove the plug for inspection. NOTE: If the top of the motor is dirty or there is a buildup of debris around the base of the plug, you should use a brush to clean before removing the plug. As always, you want to prevent anything from falling into the spark hole. To keep your small engine running smoothly, make sure you know the special considerations for using E-10 gas. Now, inspect the bottom of the spark plug for signs of excessive wear or a heavy build up carbon deposits. If need be, replace the used plug with the correct E3 Spark Plug for your particular engine.
