I have a 4-stroke outboard Honda from 1984 which works great when the choke is pulled out (including proper idle and the full range of different rpm), but when I push the choke in, the motor gets very unstable in terms of rpm and can't hold idle, it "suffocates" at lower rpm, unless I pull the choke back out.
Other things to note:
- I carefully cleaned the carburetor
- I cleaned the spark plugs with thin sandpaper
- The tank is made of plastic
- The o-ring at the fuel intake is OK, no leak
- I haven't used the boat for a couple of months, so maybe the gas has lost its octanes
- I haven't changed anything to the various adjustment screws, I just tried different adjustments for the needle at the bottom of the carburetor (fully screwed in, 1, 2 turns out), which doesn't solve anything
Thing is, this motor runs well when the choke is out, so, that already excludes a lot of possibilities
Thanks for your hints
