I just purchased a home on Lake Livingston, and a 70HP Johnson, 97 year model on a pontoon boat hanging in a boat house. Engine not started in over 12-15 months. Changed fuel, engine starts, oils way excessively, even to oil slick on water. Want to disconnect oiler completely and premix. Previous forum answers to this request drop the balance of the instructions regarding the wiring portion of the disconnect. Help with this would be appreciated. Thanks, Howard
