I want to de-carb my 1977 Evinrude 85hp but I don't have a set of muffs. Judging by what I read on this site, it makes a real mess when you restart after spraying this stuff through the motor. I shouldn't think it would be good to run the motor in a "bucket" recycling this dirty water. <br /><br />Any advice about what I should do in performing this de-carb?<br /><br />Thanks,<br />Joe
