The battery is new and fully charged up. The plus is not more than 2 months old. I put fuel line cleaner in on last fill up a few days ago and it's still gull of gas. I try to start it and it seems it doesn't have quite enough power to start. All the lights come on and when I hit the starter it turns and it tries to start unti the battery gets weak.
