Can anyone tell me where to find info about the carbon problems with Ficht motors and recommendations for dealing with it? Thanks....

Re: Decarbonizing Ficht Motor?

Hi,John.<br />The problem with carbon fouling is universal to all 2cycle engines, regardless of how they draw the fuel in.It is the biproduct of burning fuel with oil residuals. The oil doesn't burn as well as the gas, and makes carbon,or coke. It can really harm an engine by getting under the ring lands, foul plugs, and even clog exaust manifold with a black,sticky coal-like goo.<br />You can use any of the OMC,Quicksilver, or aftermarket decarb cleaners. There are two types..Additive (mixed-in with the fuel in the tank), and areosol (SP),wich is applied by spraying directly into the intake. There is a spray-type that can be "plugged-into" some of the newer injected engines,using the "Fogger-fitting". <br />These are brand-specifific, and can be found at the dealer,or shop the repairs these engines. All of them do the same job. All you need to do, is follow the directions on the particular can or bottle you buy.<br />It's a good idea to replace the plugs afterward,as they have about the same maintainance interval, and these products do strange things to the plugs (don't ask,I don't know)..But they sometimes foul quickly after decarb cleaning.<br />One other point that may not be in the instructions..You can not decarb "too-much", no matter what some might think.<br />In other werdz, it won't harm it,and can only benifit from frequent use, more so, if you idle around a bunch.

Re: Decarbonizing Ficht Motor?

Which model year and horsepower model do you have John? <br /><br />All the direct fuel injection motors carbon up differently than the carbureted 2-strokes we're accustomed to. If you use your Ficht for trolling, decarbonizing should be done every 50 hours or so, otherwise one a season or every 100 hours should be adequate. <br /><br />To decarbonize it, you'll need a couple of cans of Engine Tuner (the spray cans, not the "injection" cans). Remove the air silencer box. It's best to run the engine in a tank or barrel of water (the added back-pressure helps minimize engine run-away). Run the engine until it reaches normal operating temperature. While the engine is warming up, attach a length of string to the stop lanyard and run it to the back of the boat where it will be within easy reach while you're applying the Engine Tuner to the engine. Once the engine has gotten up to temp, prop open the throttle plates. I usually shut the engine off and use a piece of bailing wire and "tie" the linkage up to something on the block - don't wanna' catch a finger or hand in a rotating flywheel. Restart the engine and with one can of Tuner in each hand, spray them into both banks of cylinders at the same time. Try to get at least 1/2 of each can into the engine. Once you've got that amount into it, reach for the string you attached to the stop lanyard, pull it and stop the engine. In the event the engine should decide to "run-away" (term used for no-load excessively high rpm's) the string on the lanyard trick is a very quick way to shut it down without slicing a knee or other body part open on something in the boat while trying to get to the key switch. Let the Engine Tuner soak in the engine overnight. The following day, start the engine and allow the tuner to burn off - this could take several minutes. Then go for a good ride to "blow it out". If decarbonizing has never been done, repeat the procedure a second time a few days or so later. It really makes a huge difference.<br /><br />To prevent or minimize carbon build up, use the Ficht Ram Oil or better oil. I've heard very favorable reports regarding Amsoil and a few other synthetics. If carboning has been a problem, I would use Carbon Guard in every tank of fuel and have the engine checked to ensure it is running at the correct temp. Running too cool can contribute to carbon build up.<br /><br />Any other questions???<br /><br />-John
