Determine if you have DC1 or DC2 inlet seat (these have one “window”).

^{1) 2)}

If so you need to open the second window as the DC6,7,10 and 12 have.

^{3) 4)}

If so, then you can cut a second window in the seat.

^{5) 6) 7)}

^{8) 9) 10)}

^{11) 12) 13)}

^{14) 15)}

You end up with a needle seat position (read as float level) that can be adjusted on the side of the road in seconds.
Thus making the effort required to get this critical aspect of fine tuning quick and easy to dial in.
