  • 8N Engine Vibration
  • 49 8N front mount distributor and 6 volt. Have an engine vibration most noticeable at half throttle. Disengage clutch and still does it. Checked and tightened fan belt, checked fan blades, water pump is tight and not leaking. Could it be the flywheel or the crankshaft pulley and why is it worse at half throttle? Any help appreciated.

  • My first thought is one cylinder not firing. Time for structured diagnosis. No parts yet.

  • When did it start? What changes were made prior to noticing the vibration?

  • It started the vibration about 4 days ago. Just prior to that I was pushing some brush into a pile with the back blade.

  • OK, thought there might be a clue there, but if there is, I don't see it.
