Well, in order to try to track down the oil consumption in my new
Midget, I performed a compression test this afternoon.  The results
are:

  First Test
  ----------

No. 1  No. 2  No. 3  No. 4
 160     54     50    155

  After adding oil to the low cylinders thru the spark plug holes
  ---------------------------------------------------------------

No. 1  No. 2  No. 3   No. 4
 XXX     56     55     XXX

XXX = didn't take a reading


As you can see, 2 & 3 are pretty weak, and adding oil to the cylinders
does not seem to help.  I was under the impression that if rings were
going, adding a bit of oil should bump the compression up just a bit.
If this is the case, what do my readings likely indicate?

At any rate, this sure explains why the #2 plug loaded up with oil
after a long jaunt on a forest road last night.

Thanks in advance,

 -Matt (who doesn't mind if he is to rebuild the whole engine as long
        as there is no bodywork involved!)
