Sanded the excess epoxy from yesterday's fiberglass layup of the cowl bottom.
Pitched both props to 71.4 but both ended up to 71.3 or repeat measurement. Torqued the hub clamp half to 20 ft-lbs. Checked pitot position during prop rotation and no deviation from the center. Propeller tracking was within 1/16. Installed new spark plugs in the bottom cylinders and hand tightened. Spark plug gaps were all within specs.
