I had to cancel a flight and my training when yesterday at run-up the Lightspeed ignition missed really bad when checking the left ignition. Engine runs right on both ignitions and on the right ignition but very bad when switch to the left ignition.
My mechanic already checked all spark plugs an connectors, them are ok.
My airplane has only 55 hours since new.
Has anyone had a problem with their light speed ignition? If so could you share with me your solution?

Thanks in advance.
