Re: Engine Hasn.t been started in 4 yrs
Alcan is right -- and thorough. I tend to be a little impatient with a "new" motor, and want to see what I've got. At a minimum, I'll pull the bowl off the carb and clean it out. If it's clean (no gunk or varnish), I have a pretty good idea that the fuel system is probably OK. I check the plugs, and clean and regap them. If it's electric start, I clean (sandpaper) all the connections. At that point, I get some fresh gas and oil, mix about a gallon, put the unit in water and try to fire it up. The first thing to check (assuming it fires up) is whether it's pumping water. Look for a telltale and for water to spray heavily out of the exhaust port on the leg. If no water after a few seconds, shut it down and assume you need to install a new water pump. If it is pumping water, check the temperature of the head after running a bit -- should be able to hold your hand on the top of the head for a few seconds at least. You can also be checking the electricals now -- check to see if the battery is charging (need a voltmeter).<br /><br />If all goes well with the above test, you will want to replace the water pump even though it is currently working (at least you know that you have water circulation -- no blockages). The impeller is due to be replaced, and the lower unit oil replaced (and checked for water intrusion). Then it's on to the electrical system, if needed....
