I have a 1973 115 hp. johnson outboard. 2 stroke, 4 cylinder. I need a part for it.<br />I think it called a vacuum plug but not sure. Past the carb. there is the air intake,<br />and on the other side of that is 4 black plastic plugs about 1 1/2" round. 1 is cracked and when I tilt the motor, gas leaks out of it. Is there a web site where I could find one. Any help would be nice, thanks.<br />Also if anyone knows anything else about
