I have not worked on a Yamaha outboard before, hope someone could give me some advise. The outboard is a 25hp 2 cylinder 2 stroke, pull start outboard, ran perfect one day and nothing the next. It appears to not be firing, but we are getting gas to the combustion chamber. I have looked over the safety (kill switch) circuit, but do not see anything that I notice to be tripped. What is so very strange, it ran perfect, one day, and nothing the next, the easiest outboard I have ever seen to crank. I can't help but feel something in the safety circuit is keeping it from running. What do you think? I appreciate any advice I can get, Thank You.
