I have an 88 Johnson that starts and runs for about 5-10 mins. Then when it is put into nuetral it dies out. Sometimes, I can get it into nuetral or in gear and then it dies. The little red flow valve thingee (sorry don"t know what to call it.) was moved around. Could it be that the valve needs to be in the exact position? Or do I need to have the carberator cleaned or replaced? Or could it be a fuel pump issue? As you can probably tell don't know to much about engines but trying to learn. Please help! Thanks for your time.
