The handle would only turn slightly. found out the screw on the left had backed out and was catching in the handle. With an ice pick, paint scraper and flat blade screwdriver I was able to get the screw out and turn the handle all the way. I used a vice grip on the back side to hold the handle in the open position, and put the screws back in with some thread lock on them. I'll have to add this to the list of things I check on occasion. And the lock works too!
Thanks again for all your suggestions.
