Compression readings on 91 Spider



Fred,

    After a recent head overhaul (valves, guides, springs, seats, surfaces,
etc), I did a compression check on my 86 Graduate (89K miles) with a new Mac
compression tester. The readings were: 135, 145, 145, and 135 for 1,2,3 and
4 respectively. Your readings don't sound bad to me.
