Small Engines that are Smoking

Joseph Coupal - Friday, July 29, 2011

Many small engines are in good repair, but they start smoking when you start them up. In many cases, you may be able to fix this on your own. Here are some quick tips on what to look for to try to solve your smoking small engine.

  1. You may have a dirty or plugged air filter. Replace or clean it.
  2. Worn Damaged Rings. Rings and cylinder may be worn past their tolerances due to age and lack of maintenance. In this case it, bring the engine in to be evaluated for repair options.
  3. Loss of crankcase vacuum. Make sure the dipstick or fill plug is secured tightly. You may also have bad O-rings, gaskets and washers. 
  4. Scored cylinder. This is caused by ingesting dirt. Either a very dirty air filter or a missing air filter will cause this.
  5. You may be using the wrong grade/viscosity of oil. It is very important to use the proper viscosity recommended by the manufacture. It is also important to use oil designed for Air-Cooled Engines, most oils in stores are designed for automobiles with water cooled engines.
  6. Some engine failures are due to Gasoline. Either  gas sitting stagnant and clogging the carburetor, or the Ethanol in the gasoline has caused some kind of failure to the components.  The float no longer shuts off the gas and causes it to leak into the oil. This will also cause the engine to smoke and will required repair. 
  7. Leaking head gaskets. A head gasket typically leaks due to the engine overheating . Nesting or grass build up in your engines cooling fins prevent the proper amount of air circulation to cool itself and the engine overheats, warping the cylinder head causing the gasket to no longer seal properly. Low oil, Running the engine for a long period of time with low oil will also cause the engine to overheat, when the oil is then filled to the proper level it leaks by the head gasket. This situation would have to be diagnosed and repaired.
  8. The choke is still on. Open the choke as soon as the engine fires and continues to run without stoppping.
  9. There may be too much oil in the engine. Correct the amount of oil in the crankcase. Fill it only to the "Full" mark.

Leaf Blower Repair

Joseph Coupal - Tuesday, July 26, 2011

Of course it is only July, but soon enough you are going to have to get out the leaf blower. Leaf blowers propel leaves and other lawn debris by creating winds of up to 180 miles per hour. Whether you're using a back-pack, engine- driven model, or a motor-driven hand-held unit, these small machines make life in Massachusetts much easier in the fall.

Often times, after seasonal storage, we take out our small engine machines to find that they just won’t start.  Sometimes, they were failing at the end of last season, but we tucked in the garage in hopes that when we took them out again they would work.

J&J Small Engine Clinic, Inc. Specializes in Service and Repair of small engines.  We believe in complete and thorough repairs done right the First Time.
