I’d have to look, but I believe J6J is correct. J6C is the modern replacement. That engine should jump a 1/4 inch air gap while testing the ignition. How about the high speed needle adjustment? It sounds to me like it’s open to far… Try 1/2 to 3/4 open from a gently closed position. Low speed should be set 3/4 to 1 turn open from a gently seated position. It’s about impossible to get the high speed jet properly set in a barrel. You can get it in the ball park maybe, but it needs to be on a boat to properly adjust.
