Re: 50HP Force is sluggish
WOT = Wide Open Throttle<br />Tach is important because you choose the prop that will give you rpm's in the recommended range, at WOT. If your engine is not reaching the recommended rpm, then you are lugging the engine. Your engine produces its power and breathes freely at the rec. rpm.<br />Numbers should be on prop. You may have to remove it and look at the inside.<br /><br />Decarb? SeaFoam DeepCreep, or whatever you have available in your area.<br /><br />Run engine at fast idle, with engine running, 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 carbs until engine chokes out and stops,<br />remove spark plugs and spray decarb liberally into each cylinder, install the spark plugs, let it soak for 2 to 10 hours. <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 really flush it out at the lake.<br /><br />Don't do this in front of the garage door or the house, unless you want it coated with greasy crud. <br />--------------------------------------<br />You might want to check the compression after decarb.<br /><br />Keep us posted on your progress.
