Reply To: too rich, explain to me why?

the more I thought about this, I might be back to the same issue I had last year where my return line is too big. thus causing a lean/starvation issue. what is the best/ideal way to reduce the size of the line and what size is expected? I have been running close to fuel line OD with thicker wall tubing. its a little smaller but not by much if at all?

and I do not have a pump around.

fuel is good, picked it up a week or two ago.

floats are new and not stuck as far as I can tell. is 16mm the correct float level? or is it 15?
