2016 20hp four stroke Yamaha F20SEHA - electric start

Very difficult to start and getting worse. Starts but then quickly dies. After starting and cutting out 6-7 times, it eventually keeps its idle but I struggle to keep it idling. It is very sluggish at first and then after i shift to high speed it is fine. Once it warms up, it is not a problem.


Before I start the motor, i always turn the throttle to high and low three times. Is there something i could adjust to improve my starts?
