Bought this unit last year, w/o the deck, for the engine. Drove fine. Now ... no fire! Tried manually depressing the safety switches and still no fire. Could also use a test sequence with voltage specs and resistance, if available. No show at Murray or Tecumseh. The engine is a Tecumseh 17.5 Enduro XL/C, model: OHV175 ..... 204803 (H). I have automotive mechanical background but, rather lost at this point. Any help greatly appreciated .... grass growing rapidly!

I found some great diagrams at: www.partsandservice.com . However, I would like to have one for the Tecumseh OHV-175 engine and possibly a test sequence for the solid state ignition.
