24 HP twin vertical not running on both cylinders

He used to be the case or at least that's what they rated them at and often spec'd them to run but most machines now have been coming lower than that for a couple of decades.
3100 to 3200 is very common and hardly anything goes over 3400.
There are a few commercial applications where they actually state to run them at 3600 or maybe even slightly above that but that is not that common.

OK. I didn't know that. The shop manual for the engine on my commercial ZTR (engine DOM 2016) specifies 3600, so I thought that was still the norm. Thanks.

As I mentioned in the post, some commercial mowers did set to 3600 and I've seen some models spec for 3650 or 3700 etc.
 
Thank you, I set mine to 3100 mainly because it has sleeve bearings. 24hp is a lot of power to cut grass and weeds. I had weeds to 18 - 20" and the mower laughed at them. Thanks for all your help. Shirley
