jetting

[j400ex18]

when i put my 440 kit in it ran till i would go up a hill then it would starve for gas a buddy give me a jet it runs good now but would i gain any thing with a piolt jet or turning the needle (i think the main jet i changed was a 155)

i would probably put in a 42 pilot jet or so. this will help for easier starting. also, i would probably move the needle clip down one position on the needle.

I have found the jet4power meter to work very well.
