i decarbed my evinrude 120 friday for the first time.i used a can of omc engine tuner through the 4 carbs.a couple of the cylinders really bogged down and smoked a lot.when the can was empty i shut the motor down and let it soak for 6 hours.i changed my lower unit oil as it soaked and noticed a lot of carbon inside the prop big pieces of carbon.after the 6 hrs i started her up and let her run for 45 mins at about 1500 rpms hitting the throttle back and forth occasionally.she sounds great we'll see if she performs any better in about a week when she hits lake huron.thanks to everyone who gave me tips on decarbing.i new nothing about it til i seen it on this site.<br />thank you<br />scott
