yamaha 25-3 cyl issues
 

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

I will give ya 50 bucks for it ..lol

How do you know the bottom cyl has no fire?

pulled the plug, reconnected the coil wire and pulled the starter rope. come on man!!!! :confused:

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.

Let me know if u want to get rid of that yammy redfish.
