What I've done..
1)check compression...100psi both cylinders
2) replace gaskets from carb to manifold to head
3)swap coils and spark plugs to opposite side...problem still stayed with #2 cyl

Hello, the next step is going to be to check the coil with an ohm meter I'll post the info below. Let me know what you find and we can work further.

I have a service manual and both coils check good..what appears to be a bad coil will work fine on cyl #1....neither coil fires on cyl #2 ......this motor is on a Husqvarna zero turn mower.....model###-##-####

Hi and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, it would appear that almost all have been checked/replaced/tested.

Consider then cautiously adding a common ground strap linking the metal bodies (core) of the 2 ignition coils.

Also re-check the gap between the coil core to the flywheel tab.

I have added a ground to the coil on cyl 2 with same results
Customer: replied 10 months ago.
makes no sense...attached common grond to both coils...no change...then while common ground was connected to core of coils (under one of the hold down screws) I ran a separate ground wire to main ground cable of engine....no change
Customer: replied 10 months ago.
Here is something I have discovered. I have several types of spark testers..one is where you ground it and set the gap for the spark...the coil on cyl. #1 fires even if you set the gap at almost an inch...the coil on cyl#2...nothing...Then if I put the inline spark tester on cyl #1( the tester that shows spark inside of it) there is no spark...but if I detach it from the spark plug and ground the end of the tester there is good spark inside of it
