I HAVE A YAMAHA 1986 115HP OUTBOARD THAT IS HARD STARTING. iT WONT START UNLESS YOU SHOOT GAS IN PLUG HOLE OR CARB, THAN IT WILL START INSTANTLY AND IDEL SMOOTH. THIS IS NEW TO ME JUST PURCHANSED FROM A FRIEND DONT KNOW THE HISTORY. HE PUT ON A NEW CONTROL WITH START SWITCH, PROP THRUST WASHER, 2 REBUILT CARBS, RECTIFIER, MODEL # IS 115ETLJ, THANKS FOR YOUR HELP
<br /><br />Sounds to me like the cold start enrichment (choke or primer) is not working or not being used.<br /><br />This is an engine trouble and belongs in the Yamaha Troubles Forum.<br /><br />I will move it there. Good luck.
