My 3W75 quit in flight. There is no fire at the plug. Is there anything I can do other than to send it off? Anything to look at? Thanks John

Before you send it off...did you check the battery? Swap it with a diferent one. Are the connections from the kill switch to the battery and ignition all good? Did the kill switch fail? Connect the battery directly to the ignition and check for spark. Keep in mind the spark is difficult to see in bright light. Try a different plug...I know all this is common sense stuff, but just thought I would mention it.
