Z540M ?

You will need tachometer as it needs to be set at 1550 rpm.

It is adjusted by using the low idle speed screw.

Is there an easy way to adjust governor settings? My idle needs adjusting , but, I’m not sure how to do it. I found the idle screw, but, need to adjust high and low governor screws, as they have been messed with.
 
Looking further I saw the high throttle screw wasn’t touching the speed control lever at all at WOT. Also, the low governor idle speed screw was backed off as well. Is there a preset on these prior to taking it to the dealer? They’re backed up. I had never noticed them before. Basic idle is fine.
 
You must have a tach to do this.

Note: Your mower may have different RPM specs but the above should be fairly close.
 
Carefully read the instructions posted and look at the images. These are from the FS730V engine service manual

This is why you need a tach as you can't do this by ear.
 
Is it normal to have to add transaxle fluid to my z540. Both are below add. Only has 282 hrs on the engine.
Also app how many ounces to the full mark?
