Bernie, I am just curious if you watched the video that I included in my post. Sperryfreak01 contacted me about rebuilding the tach, but after watching the video, he thinks that the tach is not the issue. Could you please let me know if you did? I will add the link to the video once again... https://streamable.com/hucjjf ...please have a look and let me know if you still think that it is the tach, or if it could be something else? Thank you. ~Jeff
