I have a 1991 Yamaha 40 , my mikuni Oiler linkage is keeping it from hitting WOT , I just purchased the motor and scared to run it , if I take off the oil linkage it will hit WOT , the throttle plate with oil linkage attaches is only going to 50% open , my mikuni pump only has a wot stop , other direction goes all way to motor cowling ... what is the proper adjustment please ? Thank you very much for any help
