I believe it's a 2018 if it matters. From zero throttle to half throttle the engine is at idle at about 1600 RPMs. From half throttle to Full Throttle the RPMs increase to about 2600 Rpms (sitting still, pto not engaged). What should I be expecting on this mower? I feel like the throttle lever /...

Both spark plugs look golden brown. No real difference. Both appear healthy. Edit: That is an interesting note about the lifters/valves. I'll check clearances. To be honest, I haven't pulled a Courage apart yet. It'll be a learning experience.

This motor should have hydraulic lifters so valves can't be adjusted. But I'll pull the valve covers off and look for any anomalies. Maybe a worn cam causing valves not to fully travel or something. At least I can rule some things out maybe.

Which cylinder is the problem? 180 is too high isn't it? 140 is a little low, but very acceptable for an engine with hours on it. Right??

Follow up post. I disconnected the main harness and direct connected 12v to the DSAM and the Solenoid. Motor fired right up with no issues. Revs up and down (no load) easily. Must be something in the main harness. Luckily I don't need that. To the trash can it goes. This is just a spare motor...

I don't think this is the issue. I've triple cleaned the main engine harness plug and it looks good. However the rest of the harness is complex and just laying all over the workbench. So it's possible there are deeper issues involved in the harness as a whole. I'll be removing the harness later...

Yep, thanks. I've got it on my bookmarks already. Invaluable with these motors.

Yeah good point. If feels like the source of the issue is the DSAM since when disconnected the voltage shows right. But maybe it's simply the normal load of the DSAM that is overpowering the system from a separate issue. When this was on the mower I checked spark on both cylinders and I was...

The short video attached should explain it better than I can. Essentially I'm not getting 12v to my fuel shutoff solenoid unless I unplug the 12 volt lead to my DSAM. One thing to note in addition to what I mentioned in the video about unplugging the other leads to see if anything changed...

Ah, good point. Won't bog down so easily. Makes sense.

I've got an Ariens Ikon X 52 that came with a 22hp Kohler Courage motor. And I have a 26hp Kohler Courage sitting in my garage. The motors look identical even down to the shroud. I'm guessing it's just a longer stroke or a slightly bigger bore to get that extra 4hp. So... stupid question I...

Thanks. That's even more a mystery then. I'm left to wonder if it was replaced with NOS somehow or a full used motor. Probably the latter. No idea what the true hours are now. Ugh. I'll have to research if it has compression release to know if I can even get a compression reading to gauge the...

I just bought a 2018 Arien IkonX 52 and noticed that the Kohler Courage 22 that is on it has a "build date" of 1/31/2006. Anyone know if that seems normal? A motor that was built 12 years before the mower? Or should I assume this has a different motor than what it came with? Just curious really.

I don't think only having the blades engaged while sitting still would constitute a real load. The rpms with the blades engaged were 3400+ just sitting there (that's why I ruled out the deck being an issue). It's a moot point at this juncture anyways, I just sold it. I sold it for more than I...

This spins free. But if it didn't, this would present itself even at idle. Not just under load.
