I am in desperate need of help. I have been working with my 1995 9.9hp evinrude outboard and I just can't fix the problem. The problem is when I throttle up the engine it sputters and dies. The engine starts first pull and runs full open when the choke is pulled out. The problem starts when I put the choke back in and crank it up, it just dies. I got brand new spark plugs (correctly gapped), so I am not sure what else I can do. Please help, really want to get on the water.
