  If your Echo engine won't start, there are several potential causes. First, check for a lack of fuel or oil and fill the fuel tank and check the oil level. Next, make sure the spark plug is connected. Also, the kill switch on the access cover could be damaged, so test it and replace if necessary. The fuel might be dirty, stale, or contaminated, in which case you should drain and refill the fuel tank with fresh, clean unleaded regular gasoline or diesel and replace the fuel filter. If none of these solutions work, there may be internal engine problems and you should consult your engine dealer.

  If your Echo engine overheats, it could be due to a plugged cooling system. Try cleaning the cooling fan and cooling fins on the radiator or engine block. Another possible cause is an improper coolant level, so fill the engine to the correct coolant level, referring to the engine owner’s manual for guidance.

  If the Echo engine stalls or the belt squeals when engaging the belt on your Echo, it might be that you are engaging the belt too fast, so reduce the engagement speed. Another potential cause is that the belt tension is too loose, so adjust the tensioner and replace the belt if needed.
