Compression figures

[Richard J Lebens]

Just for reference -- When I got a 60 reading on my 20 valve it was due
to a running rich condition, once from a bad fuel injector and once due
to the distributor filling with oil.  After I fixed the rich condition
the compression healed itself.  I suspect this was due to carbon/slime
etc. on the valve seat.
