Hey, guys so I just recently bought this 1970 Evinrude 6hp. the guy I bought it from said carb was cleaned and rebuilt but the carb is leaking from the lower seal. The motor will only idle a little bit when just barely under the start position. I have tried starting the motor and letting it run just below the start position 1 1/2 turns counterclockwise then 1/4 clockwise until it stalls and it never seems to stall whether I turn it completely lean or rich. I have noticed when I am making 1/4 movements it responds sightly more but never dies. will not idle at lower RPMs like it should and will die out if below this start position.
