Changed to a 180 MJ. put in a new clean plug. Ran around a little track in the yard about a mile. Still no spooge, plug insulator is brown on one side, ground electrode is just as clean as when it went in. Do have some exhaust smoke when gassing it. Seems a little more doggy just before hitting the pipe with the 180 mj vs the 172, you can even hear it. Think I'll try the NEDH needle again and see how it does with the larger mj.
By what I've read the NBHW is the stock needle. There is mention of it
