69 is right, you need to raise your float level so its running out lightly when idling.



When I say 2-3 flats, I mean the nut. Lets say you adjust it where its coming out. After that, turn the nut an additional 2 - 3 flat part of the nut on the needle/seat assembly. That way you can keep track of how much you turned it and then see what happened and go back easy

However, it does sound like your float level is low.

You may need more powervalve, but I doubt it.
