I have a 2004 115 h.p. Yamaha 2 stroke w/manual choke. It has been nearly impossible to get it started when cold i.e. first start up in the morning. After it finally gets started it will start right up after that all day. It was always a little hard to start but now it takes about 15 min. of playing around with it to finally get it to start. I took the cover off the carbs and the butterflies seem to be working as they should. When I put my hand over the bottom carb and completely cover the carb it fires right up. I'm at a loss as to what could be causing it to act this way. I don't use Ethanol and last year I had a new fuel pump installed and the jets adjusted. Any thoughts on what the problem could be? A local Yamaha expert said there was a few years where Yamaha had bad chokes. Anyone know about this?
