"Hi all, I am new to boating and have some problem with my 15hp 2 stroke engine just bought used.
It starts and runs on idle but sneezes and stall sometimes. then starts again - no problem.
when i accelerate it sneezes more often and doesn`t give power. when I start drive my dinghy it doesn`t have power to move it well.
BUT... if I close an air a little bit it starts run much better and I can run my dinghy pretty well. On full speed I tryed to open an air fully - it loosing power right away! What it could be? Please, I need your experience guys!
I checked a carb looks pretty clean inside, chenge spark plugs....
Thank you!"
