Finally got it open. I disconnected the linkage from the release lever under the dash and pulled on it with a pair of pliers while my wife lifted up on the front of the hood. There doesn't appear to be any adjustment. I gave the latch mechanism a shot of WD40 and it works okay using a pair of pliers. Reminds me of the days when I owned an MG.
Honk if you love Jesus. Text while driving if you want to meet him.
