Mower is not running good on one Cylinder no power sounds terrible when idled up, pull sparkplug wire off plug when running and you can hardly tell the difference on one side. Has poor spark on one side good on other. put new coil pack on the bad side and still acts the same doesn't run good on one side pull plug wire and it acts no different any suggestion's.

Remove the blower housing and remove the small wire on the bad coil.
Start the engine if the bad cylinder suddenly works well then the wire that joins the two of them together needs to be replaced.
It has a diode in there to prevent one interfearing with the other.
You will need to put the small wire back on to stop the engine ( or pull off the plug lead.
Don't run it for more than 10 minutes without the bower housing off.
