Hello everyone,
 
I have a Husqvarna YT48XLS with the 26HP Kohler motor and I'm not getting any spark to either spark plug. To try and fix the issue I did the seat safety switch delete, tried different spark plugs and checked the oil which is on the full line so it's probably not the low oil shut-off.
 
If anyone has any suggestions please let me know. Thanks :)

Disconnect the small black , KILL wire from each coil.  You should have spark..

Ok thank you, I will try that. Hopefully today I can get to it.

So the problem is that the mower needed 2 new coils, it now runs but hesitates a little bit. Just to confirm, what is the correct air gap for the coil on my engine and what is the correct spark plug gap?
 
 

A business card (about  .010") will work fine for the coil air gap.  
 
Spark plug gap for that big an engine , gap is usually  .030"
 
Both coils going out at the same, highly un-likely. Please post back how it goes..

Thanks for your reply. All I know is that both old coils had intermittent spark but the new ones make the mower run.

Great!   That's what counts!  

Is there a difference between the left and right coils on this engine? I ask because one coil has a slightly different number than the other. Left side is 1522907 and the right side is 1522906. Any other info. about mounting them would be appreciated too for instance which side goes up and which side goes down.
