Nice yard-cart you have there Stuart. I'm assuming the orange one is a sprayer? Looks like it can hold
quite a bit of liquid. How much area do you have to spray?
The owner's manual isn't much help for the creeping problem, as it only states-
"To prevent the machine from creeping when in neutral, perform the following steps-
1)Move the lever back & forth in the neutral slot area to find the neutral position.
2)When you cannot stop creeping, consult Yamaha dealer."
I'm sure there's an adjustment procedure, but can't tell by looking at the parts drawings.
