yamaha 25-3 cyl issues

[redfish150]

i have a yamaha 25hp - 3 cylinder, bottom cylinder not firing.
Pulled each plug to determine that bottom cylinder not firing.
Swapped the 3 coils around moving the top and middle to bottom and still no fire.
Changed the CDI (power pack) and still no fire at bottom cyl.
Good compression - 120 all 3 cyl
getting fuel at all carbs

Any suggestions?
Rectifier? should i change it? could that be it?
Thanks

That is not always an accurate test . If you have a bad plug it wont fire,if the plug isnt grounded good it wont fire .
Im trying to help !

I have a spark tester, I live in Moss Bluff. If I remember correctly, I have seen one or two of those motors. PM sent.

Kenner, didn't mean no harm. I know its not completely acurate, i tried different plugs and tried it several times.
no spark tester, just doing it the poor boy way.
Thanks for the help.
