Yamaha 1997 8 hp 2 stroke outboard. Need timing, carb, throttle settings

SOURCE: 40hp 1987 yamaha outboard motor will run for 30-60

Sound like the fuel pump is not keeping up with the engine's demand. Check it out. Good luck. Hope this helps.

SOURCE: l50deto 2 stroke outboard stalling at high revs

fuel pump could be the cause but also the float in the carby could be not set at the right level and starve the motor at high revs .

Testimonial: "I found the solution, carbs werent clean enough. Got a compressor in there and solved it. Thanks anyway"

The correct gap is .035

On the tachometer back you have secured a wire thread just like the one from the brakes of a bicycle. The other end of the wire is secure to the engine. This wire complete, need to be replaced.

As a test first disconnect it from the tachometer and see if ok if not then the problem is with tachometer.
