Fixed a couple of issues from the first engine start. Two fuel fitting had minor leaks. Redid the fittings due to my assembly error. Tightened some of the radiator hose connections due to small leaks that were found. Changed the oil on the right engine due to fuel contamination from the defectiove primer solenoid. Rewired the power to the starter switches to resolve the Verticle Power feature. Temporarily fit the rudder to mark the paint trim line so the painter can match things up without the airplane.
