Used octane engines

Used F1/F2 units capable of research or motor method rating. One 1993 Waukesha CFR F1/F2 is available for inquiry; hours, serial and condition are confirmed on site.

Before viewing

Check these first

  • Single method or research/motor combination
  • Control cabinet: classic gauges or digital — follow the nameplate
  • Photograph the serial; write “unknown” if hours are unclear
  • Whether cylinder, carburetor and knockmeter are still a matched set
  • Whether cooling, exhaust or foundation were modified
  • Missing tools and reference-fuel system listed separately

Refurbishment is usually written as: seals and gaskets; top-end or carburetor by measurement; instrument zero; safety guards; observed run-in. Not warranted as new.

Next step

Tell us the engine model, the symptom, and the last rating run

A nameplate photo helps: research method, motor method, or cetane, and where the reading drifts.
