Aloha,
I just purchased a boat with twin suzuki 70 hp fours stroke motors.They have 170 hrs and are in great shape.The previous owner did not run the boat for about 5 months.Now one motor dies out when throttle is put back into idle.The code that comes up is a 3-1 (Iac valv/by-pass air screw adjustment.The manual says to hook up a engine tach. and follow procedure to adust.Guess my question is are these engine tech expensive to purchase or due I really need it to adust the by pass air screw....any ideas
