Re: Spark Plug Gapping 82' Evinrude 70hp
Deuce. Decarb is sold in cans (spray) and also a fuel additive. I like the spray.<br /><br />This is how you use it.<br /><br />Start your motor and get it warmed up to normal tempature. Now spray the decard into each carb throat while the engine is running. I have 3 carbs, but you may have more or less -I don't know.<br /><br />Anyway - as you are spraying the decarb in increase to a faster idel. (you can use your other hand to rev the engine from inside) The engine will want to die as you spray this stuff in, but don't let it just yet.<br /><br />The engine will also smoke like heck, but don't worry.<br /><br />Now after you have used the entire can shut the motor off and let it sit for about a half an hour.<br /><br />Now start it back up and rev slightly higher than normal for a few minutes. Again - the engine will smoke like heck and smell.<br /><br />After you are fininshed CHANGE the plugs. I don't know you gap, but you should be able to find it online.<br /><br />The decarb will clean the carbs, free up stuck rings and make the engine run 100% better.<br /><br />You should do this at least twice a year. The decarb runs about $8.00 a can.<br /><br />Good luck.
