Re: 89 85hp force not starting
Do you have an electric "choke" solenoid on that engine? Is it working? It is actuated by pushing the key in for 5 seconds before trying to start.<br /><br />Does fuel line bulb stay pumped up firm?<br />Have you checked compression?<br />What do the sparkplugs look like?<br /><br />Has it always been like this, or did it just start happening?<br /><br />In addition to just adding a cleaner to the gas, you should do a decarb of the engine. It is reommended by the manufacturer.<br />***************************************<br />Decarbing is a 2 part process. The first part is preventative, done by using a fuel additive to prevent carbon build up. SeaFoam or Ring Free are such fuel additives and can be found at most auto parts stores. It also works as a fuel system cleaner and should be used as a preventative maintenance procedure.<br /><br />If Your intent is REMOVE the existing carbon buildup from the cylinders, heads, and rings, a spray decarb solvent product, such as SeaFoam Deep Creep, is needed. Some people use one can per cylinder.<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 /><br />Remove spark plugs and spray decarb liberally into each cylinder, install the spark plugs, let it soak for 2 to 10 hours. <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 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.
