Evinrude Lightwin 3 identification help

Info Please, I have a Lightwin 3 serial number 3018-09071 can anyone tell me the year, correct spark plug and fuel mixture.  Also there is a tube that goes alongside the motor leading to the carb, does this require a sponge type air filter?  Thanks in advance.  Pappy

Re: Evinrude Lightwin 3 identification help

Your motor is a 1956 model, and it's 56 years old this year !!!!!

 

Use the Champion J6C sparkplug gapped to .025-.030".  I believe those motors originally used a 16:1 fuel-oil ratio, 8 oz. ( 1/2 pint )  oil to 1 gallon of gas.  With todays better outboard lubricants many folks run those motors at 24:1.  That motor has brass bushings and not needle bearings so it needs a lot of lubrication to run well.

 

There is no foam air cleaner but may have had a perforated screen in front of the carburetor and held in place by the long tubular air silencer.
