This is the Instruction & Tune-Up Manual for the floor model ATLAS Motor Analyzer. The copyright date is 1946. 40 pages. Direct from your neighborhood Standard or Chevron gas station!
In addition to illustrated testing hook-up instructions, the manual also includes a section on tune-up training. This covers the operation of the various engine, fuel and ignition components.
Shows use, but is 100% complete and reasonably clean. The front cover is not securely attached any more, but could easily be taped in place, if you wished. The price for this vintage ATLAS Motor Analyzer is just $15, plus $5 shipping. Thanks for looking. John
