140L problem

[Jim Ivey]

Todd
It could be fuel. I had similar problems when I was using a metal (alum) container to pump my fuel from. Something caused contamination and every time I poured in new fuel the engine would run ok for a few tanks ,then act up again. ...So now I pump from the plastic jug that the fuel comes in.
