1994 Yamaha Waverunner iiiGP fuel issues
Good day, total noob here and I have rebuilt an older Yamaha Wave runner. New crank,rings and carb. It will not stay running.
I was able to get it to run off the spare tank when it was first reinstalled. I drained the tank of all the old fuel and water that was in it.
Now for some reason it will not stay running unless I bottle feed it with some pre mix.
I am able to get it to start but only by covering the intake with my hand, has plenty of pull and good compression.
But once I remove the choke and my hand it will stall out. I am trying to figure out were if any it could have a vacuum leak.
Does anyone have an idea to to go to next on the diagnosis?
