[Roadsters] Compression test re: engine health

[dave]

Doesn't sound too bad, consistent compression is more important than the
actual PSI.  Get the carbs done, they probably have leaking throttle
shafts and see how it is.  Did you desmog the distributor with a 7.5
advance cam?

Subject: [Roadsters] Compression test re: engine health

Being a new Roadster owner ('68 2000), I'd like to assess the general
health condition of the engine. I've rebuilt the distributor, replaced
the plugs, coil (MSD), and wires (MSD). I checked the compression today
and each cylinder registered 145 psi after 5 cranks. Is this acceptable?
What would a leak-down test determine compared to todays test? How do I
perform such a test? The car doesn't burn any oil but occasionally blows
some smoke (running very rich, need to replace carbs). What is the
tell-tale diagnostic that would reveal serious engine concerns/rebuild?
   
  Thanks!!
