Re: Motor still runs rich,spark is good carbs are clean Decarb?
Carburettors don't "carb up", the carbon is a result of fuel burning which it only does in the cylinders, you will never get carbon deposits in the carburettors.<br />The carbon in the cylinders is a result of running rich, if your carburettors are clean and all the seals etc are good, then they probably need adjusting to lean them out.<br />If it's a 2 stroke the carbon buildup may just be a result of prolonged idling. They do prefer, and are designed, to be operated at high speed and tend to run rich at low speed.<br />This talk of "carbing" and "decarbing" can be confusing if you are unfamiliar with engines, "carb" is just short for carbon and has nothing to do with carburettors!<br />Many years ago when I rode 2 stroke motorbikes we called it "de-coking", afaik it's still referred to as that over here, it's much less confusing.
