Started up an 86 2.1 the other day to test compression to determine
its future and 2,3,and4 were all in the 135-145 range, but #1 was at
90.  Motor doesn't run all that well, so it's hard to tell and it is
dealing with the noisy lifters issue.  I'm curious if it's possible
that the lifters are sticking and creating the low compression, or
whether I need to move on to a leak down test and/or squirt oil in
the cylinder to see if the compression goes up.

Any thoughts?  I know Bob would've had the answer.
