If this is not the case rotate theĬrankshaft one full revolution. The valves of the no.2 cylinder must either be crossing over or the no.1 cylinder must be at the end of it’s compression cycle (feel pressure buildup by closing the spark plug bore of the no.1 cylinder by closing it with your thumb while rotating the crankshaft). starter ring gear lines up with the parting surface of the crankcase (on the L 2400 EB1.AD the timing pin P/N: 803.001.125 fits through a bore in the accessory case and must engage with a notch in the fly-wheel). Rotate the engine at the crankshaft until the timing mark on the propeller hub resp.
