OK, no squishing then. Just start it up cold, run it just long enough to pump them up, measure the lash, then wait a while and see if the lash grows. Of course, a true mechanic would bill out the time that you sit, wait and watch for that lash to grow. A
great mechanic would do several cars at the same time and bill the watch and wait time to all of the owners, with no
pro rata discount, of course.
