Re: Carbon Buildup
Bluefish, to answer your question about additives adding octane,let me elaborate..<br />I have one engine (Force 50HP), that wont even run with decarb or sta-bill additives.<br />I tried using the ValTect at half the recommended dosage, and it runs fine. I have,however, had a plug foul.<br />Any time we add anything to fuel,whether it's Sta-Bil or mineral spirits, it raises the octane level of the fuel. Off-the-shelf octane boosters are little more than mineral spirits in an expensive bottle.<br />Rule of thumb is, the higher the octane, the less explosive the fuel is.<br />BobMoore, I don't think it was running too cool because the cylinders were clean.<br />But it did run too cool if the t-stat stuck open. I would be more concerned that maybee spotless cylinders would indicate too little oil in the mix,or a lean-burning condition from fuel starvation. That can destroy an engine faster than heat.<br />Like ODDD1 said tho,(loosely qouted here) "carbon in itself is not detrimental if it is controlled. The problems come-in from cheap fuel".....<br />I will add to this tho, that too much carbon fouls plugs, sticks rings in their pistons, plugs muffler-equipped 2 cycle engines, and gums-up reeds. <br />It can also get so bad, that additives or fogging can't make a dent in the stuff.
