2003 yamaha 115 4 stroke flooding out

[ferrellrooster1]

Hello,
My 2003 yamaha 115 4 stroke is flooding out. I use it reguarly and it does not sit up very long. I usually hook the hose up to it the day before I take it out. And did this time and it worked fine. I dropped it in the water and it started then died. Then would not crank at all. I took the cover off and trimmed it up and about a cup of gass poored out of it. Seems like a stuck injector But I have read of other things that it may be other than this. Like the VST? ISC valve? I would Like to check these and clean them but I have no idea what they are or the abreviation stands for to even start. Thanks in advance.

The VST does have a float with needle valve like a big carb. If it doesn't seal, it can flood the intake with fuel through the overflow line. It is a pain to get to. You must remove the intake off the port side and its attached to the back of it.

Thats kinda what I was thinking. Just didnt know for sure. thanks for your help. I work long hrs. 9am-9pm So it may be a day or so before I can report the outcome. Or if this was the prob. Either way I have never seen so much gas poor into an engine as this. thanks
