psdenno Posted February 11, 2015 Author Report Share Posted February 11, 2015 Champion J-61Y...it also had a different gap...from the side. Recommended gap was .018"-.023". We have a WINNER!!!!! Champion J-61Y, 2nd step cold is correct. This answer has now elevated you to the Senior Division of Avanti Trivia Grand Masters! From now on, I can either email the questions directly to you rather than posting them here, or do the Jeopardy thing and post the answer and you guess the question.
