HI Guys, Newbie with a problem here...I buy restore and collect 3 hp Evinrude/Johnsons and I have a problem. I have one which is almost restored with virtually everything new but it runs, or seems to run very rich and oily. It starts without choke and only runs at low revs with lots of smoke and an oily residue below the water/exhaust ports on and down the lower leg. The only time it runs sweetly is when I turn off the fuel tap to run her out of fuel and then it's for a few seconds till she stops.
To aleviate the problems so far far I have
Cleaned the carb twice with new O rings. Still using the original cork float but new needle and seat ( but not the main bowl gasket nor the main high speed needle which is more like a bolt with no tapering )I haven't a new one in yet
Changed the top half of the carb with another one but again no gasket or main needle
Changed the main internal jet
Checked all the electrics, plugs and points again
Checked the fuel ratio twice even ran her on 100/1 just to make sure it wasn't the mixture.
Checked exhaust for blockage
Checked the carb connections etc etc
I'm so close to getting back to her former glory but this has me stumped
Any idea....thanks
