    Hi Bruno, do another test run and see if there is misfire while the engine is not yet too hot. In case you have ignition trouble from the start you will no doubt find the dead mag. But if the motor runs OK so there is no problem with ht wires or mag cap etc. . You could do a test flight around the airfield for at least half an hour to have a real warm engine and do a mag test in the air and see what happens if you want at least 80 % revs. If you get misfires you will have a duff coil/condenser and need a rewind. To do another check : Put the suspicious mag in an oven at 80 degrees C for an hour and test the sparks by flipping the drive shaft by finger: You should see a good spark of several mm, if you dont , well .....

    That could be as simple as a broken "P" lead wire. Presumably you had a good mag. check before the last take-off but if you had a failing wire it could have finally separated in flight. Take a good look at the wire going into the aft side of the mag. If not obviously broken do a continuity test of the complete primary circuit. If you are not fully familiar with magneto operation I would suggest that you contact a licensed aircraft technician to help you.
