I had noticed the upgrade to a 24 hp honda. I was hoping someone had done it. I am curious how the engine with a sprocket adapts to the spline coupler. Not sure if the shaft under the honda sprocket was the same taper as the spline on the 582. Had a difficult time getting that spline off the shaft to check sizing. Wondering what other mods where needed and how complete the installation kit is. It would be great if you would give an update when you check it out. Thanks for the fast replies. I appreciate all the info guys.
