Problem solved. For all of you who contributed their advice, it was greatly appreciated. Here's what we found: We went in and checked all the pitot and static connections first, and reconnected them with good old pipe tape to be sure there were no leaks. The test box said all was ok, no leaks. But, when we flew it, it still read high...some folks have mentioned to check the gps. Well, i know the GPS was accurate in calm winds, because if I didn't maintain 80 or 85 on final, she'd drop like a rock. She lifted off at 80 on takeoff. So, yes, we tried a different GPS, and did cardinal headings, in case there was a knot of wind. Bottom line: Pitot static box tester said all was well, but when you fly, it read way too fast. Last night I spoke with Georgia's finest Ercoupe mechanic, who just finished my $6000 annual/restoration with me. He said to measure the distance from the leading edge of the pitot tube to the bottom of the wing. It should be 3 7/8 inches. Mine was 2.5 inches. We gently bent the pitot tube down slightly to the correct angle (3 7/8 inches from the wing) and wonder of wonders, she lifted off at about 63, and I flew a comfortable final at 65. The GPS now says right on, no wind. (GPS is in MPH, as is Airspeed indicator). Also , my cruise is 103, which we all know is right, for the cruise prop. So who'd have thunk it? It's truly nice to know how fast you're really going! Thanks again to all who offered help with this interesting problem!
