Corroded terminals on your twenty year plus old wiring harness could be the cause of running terribly. Unplug all connectors and check for corrosion, clean as necessary.
110 PSI would definitely keep the engine from peak performance. But it wouldn't explain chugging down the road at top speed of 25 MPH.
I gotta agree with Holun on jumping the gun with engine replacement. On a really old engine that has been ill maintained and not driven for years, gummed up rings could be cleaned up with solvents and some driving.
