90' Yamaha CV85ETLD. Engine new to me. Previous owner rebuilt carbs and stated that he tuned it last time it ran 8-12 months ago. What's the procedure to adjust the carbs? Or should this done in the water and if so how? Just back off the water from a very frustrating first sea trial. Engine would run at idle fine, start fine, and then go into reverse with power. After that all down hill. Motor would cut out every time I tried to put into forward and then no power to start? Try again in idle no power to start...tilt motor works fine up and down. Somehow it will start again then same thing, fine in idle, dies out trying to go into forward gear. Then no power to start. Paddle back to the dock. Take it over to the boat yard, put it on the flushers, engine starts fine multiple times, and runs in forward and reverse. It still breaks up over 3500 rpm. And yes there is no load. I now have no confidence to go back out again without addressing the issues The biggest issue I "smell", is that it is running very rich and reeks of gas. A lot of gas. I have a separate oil injection unit feeding the motor. I also charged the battery just in case for 6 hrs with good readings before heading out. Any help appreciated.
