The last couple of days worked on various odds and ends. Finished riveting the tail and clecoed the stab tips back in place. Installed nutplates on access hole for the Ray Allen stab trim. Started the engine again and initially found a loose nut on the Aux fuel pump. We removed the fuel manifold, tightened the nut and then reinstalled the manifold. After that the engine start went smoothly. Ran the engine for about 10 minutes and found no further problems.
