have a 75hp that has a slight slow idle miss. when you apply a little more gas it seems to level out. runs like a champ from that point on. Also motor runs cool . after running for about 30 min at half throtle removed cover and the motor was not warm to the touch. Could a hotter spark plug help, if so what is the hottes plug for this unit.
