One thing to try before a second compression test is to find a good straight stretch of quiet road,and run the car hard in second gear,then take your foot off the accelerator and let it pull down to idle in second gear,repeat four or five times..this forces the rings to work in both 'directions'..then take back to the shop and compression test while its still warm..
