If the PO says it hasn’t run in two years they probable really mean four years.  Chance’s are the rings are sticky.  Compression numbers on motors that have been stored a long time really don’t mean diddly!  JMHO  Expect the worse maybe if it will run even poorly it will come back to life for you.  I have four 18’s all of them had issues.   A little TLC and they can become great runners.
