Been very wet here so couldnt use the mower until tonight. Afraid there's no happy ending. It starts fine, runs anywhere from 5 secs to a few mins and then stalls. Still has spark after stalling but perhaps not as strong as it is before i turn it on ie not as bluish. It has a stuttering rev motion rather than a nice continuous rev. Even though it stutters when it runs it still works fine. Full throttle still stutters only louder.
