Re: 1994 Force 120 Compression/Decarbing
WHat LubeDude said.<br />So what do you call a service tech that doesn't know what decarbing is, even though it is recommended by all the manufacurers?<br /><br />Answer: Useless, all to common, but useless.<br /><br />Decarbing:<br /><br />Your intent is to REMOVE the existing carbon buildup from the cylinders, heads, and rings, a spray decarb solvent product, such as SeaFoam Deep Creep, is needed to do the decarb process. Free moving rings are what seals your cylinders and gives you compression. Compressed and stuck rings meanss loss of compression, broken rings, and eventually, engine failure.<br /><br />Run engine at fast idle, with engine running and warm, slowly spray liberal amount into each carb. Its gonna smoke up the place. <br />Spray for a couple minutes, now spray a larger amount into the carb(s) until engine chokes out and stops.<br /><br />Remove spark plugs and spray the decarb product liberally into each cylinder, install the spark plugs, let it soak for an hour or more. <br /><br />Start the engine and run at medium throttle, or if at the lake, run it at full throttle. It won't hurt to spray some more through the carbs. Run it for atleast 10 minutes to flush the crud out of your engine. Now remove and clean, or replace the spark plugs. <br /><br />It works well to do the spraying, the night before you go to the lake. This way you can let it soak overnight, and run at full throttle at the lake.<br /><br />Don't do this in front of the garage door or the house, unless you want it covered with greasy black crud.
