Hello everyone,
I recently purchased a 16 ft crestliner with a 1961 evinrude lark 3 40 hp motor.. Model number 35525
Brought it out to the water where she ran but eventually bogged down and shut off.. Upon restarting, I had gas spitting out of what I believe to be a vent hole.. Disconnected the fuel line and tried getting some of the gas out of the motor.. Let it still for a while and started back up and we rode a solid 25 minutes and both full throttle to slow wake zones without a problem.. Than.. Again... Bogged down and quit again..
I took the carb apart and cleaned everything with carb cleaner and compressed air, upon taking the carb off it appeared to be clean before I even cleaned it. Put it back together and fired up the engine and it started up and sounded good.. No gas spitting.. Shut it off and tried a little later.. This time spitting gas out again.. When pushing the bulb of the fuel line it stays pressurized upon pumping but as we'll shoots it through the carb.. Took it apart again and got fine wire and cleaned everything again.. Started it up ran good.. Brought it to the water.. Same thing spitting gas..
What could it be? The needle was a rubber tip so I don't know if that can go bad, also float is cork so maybe the varnish is off causing the float to sink? If so, why would it allow me to run as a strong engine for a while to quit right back down? I am going crazy here to figure out what's wrong..
Thanks in advance
