Default Hard starting 4-stroke outboard

Motor: 1996 Johnson 15 hp 4-stroke, model J15FREDR. About every 3rd trip,
the motor needs a million pulls to get it started. Primer bulb is pumped
till hard, as always. Once it starts, it runs smoothly and it will restart
effortlessly all day long, requiring a very light pull on the rope. When
shutting down the motor, I always let it idle down for a few seconds. I
wondered if tipping the motor up at the ramp might be a factor, but that's
rarely necessary at the ramp I use the most.

Best answer gets 15 virtual beers.



The cable operated choke may be out of adjustment, not allowing the shutter
to close completely. Losen the clamp screw, pull the choke closed, and
take any slack out of the cable, then tighten things back up. You do need to
advance the throttle a bit for a quicker start.

Richening up the idle adjustment screw can also help starting and warmup
time.
