It is essential to go straight to the heart of the matter, so to speak, the engine! There is no better way to evaluate an engine than to turn it on, run it and keep a lookout at the engines exhaust. Listen to it. How a cold engine runs could tell you a lot about how well a grinder has been maintained. Another tip is to see if there is rattling / shaking going on once the clutch is engaged. This may indicate a mill which is out of balance and should be corrected prior to purchase.



Back to the exhaust, the color of the exhaust smoke the engine produces can provide great insights such as:

  • Black smoke typically indicated that the air / fuel mixture is too rich in fuel. This could be caused by a number of issues from faulty fuel injectors or a simple fix of a dirty air filter.
  • White smoke could mean that the fuel is burning incorrectly. Maybe a faulty head gasket that lets in water, mixing with the fuel or there may be a compression issue.
  • Blue smoke means the engine is burning oil. Most commonly caused by a worn ring or seal but it may be as simple as an over fill of engine oil.
These are just a few suggestions of what to keep an eye out for. We welcome your input as well.
