During tests we have found that Suzuki DF 40/50 Four Stroke series engines, the engine control unit sometimes stores a CKP Crankshaft Position Sensor error, and that the engine (Fig 1) does not run correctly in this condition.
After checking that the sensor was working correctly (resistance of 168-252 ohms and 20°) and the viability of the electric system, we found that the problem was caused by incorrect timing of the flywheel during ignition (Fig 2). This was due in turn to the key having been knocked out of the flywheel and not to any sensor malfunction.
In this situation it is necessary to re-time the flywheel during ignition according to the manufacturer's specifications, and to clear the errors stored in the control unit.
