1983 Johnson 140hp - tune up...carb help....

[ohyeah829]

Hello. I have an '83 Johnson 140hp v-4 that I am getting ready for the spring....I started it for the first time since last year and it's really smoking. It smells like an exhaust smoke, though. So, I syphoned all of the gas out this evening. Also, I replaced all of the spark plugs late last year (first time I've ran them). I haven't got to refill the tank yet, but is there anything else I can do to get it running smooth?? I've been reading a lot about carb cleaning and stuff, suggestions?? Thanks!!

ohy,<br /><br />Where do I start?<br /><br />If it were mine, I'd do these things.<br /><br />1. Buy a manual.<br /><br />See here: <br /><br /><br /> http://www.outboardrepairs.com/manuals/ <br /><br />Best $30.00 you'll ever spend.<br /><br /><br />2. Add a water seprator to the fuel line.<br /><br /><br /> http://www.iboats.com/mall/index.cg...keywords=fuel+filters&submit.x=56&submit.y=13 <br /><br />3. If you do not know when the water pump impeller was replaced last-YOU'RE due.<br /><br />4. If it's an oil injected model (sure it is) then drain/dump the old oil from the tank and refill using ONLY a good TCW-3 rated outboard oil. Note: Mix the fuel 50:1 with outboard oil until you can mke certain that the oil injection is working; read-using oil.<br /><br />5. Drain and refill the lower unit using a good lower unit fluid (OMC/Bombardier) preffered. Make sure to replace the lower unit drain/fill plug gaskets. Cheap insurance.
