It's an 85 1.9 with about 104k on it.

Drove it 30 miles at freeway speeds, 60 to 72, today and it was running very
nice.  I could hold about 68 just touching the second butterfly.  Trying to
burn off about 3 gallons of 1 year old fuel mixed with fresh added up to
whatever the full tank holds.  Going to add a can of Sea Foam before a run
after work tomorrow.
