a 2x4 setup question

Hey AJ, I just got a good eye full of a (IIRC) 1916 REO. Carb is at the driverside, bottom at the frame rail. Intake 1-1/2 straight up.
Gas tank filler under passenger seat.
Starter button on the floor next to the gear shifter.
What a blast listening to the owner answer questions. Talk about things you would never expect!!
