Where is my compression and vacuum??

true on the pressure, but they'll run 180 out. not well, but it'll make a go of it.

the "ah-ha" moment comes when you've cranked the unit around until the VC hits the firewall and you think: hmmm... i don't remember that....

anyway, is it just my thinking that 90psi cranking compression is dreadfully low?
Yes, that's pretty low. At least it's consistent though which is a good sign.
