I found a bunch of fluid leaking out the bottom. My assumption is it must be engine oil, can’t think of any other fluid it could be.

I did find a nameplate on it that was caked over with dust. It’s a Kohler 2.5CMZ, so at least now I have the owners manual on how to check oil etc before trying to fire it up

The only fluids in it would be oil or gasoline. Since it's propane, no gas so it must be engine oil. condensation would evaporate and return so that would be in the form of water but it wouldn't be much. Rain water? I pulled my genset out and replaced three times. I payed a man 750 to do it for me once. If it doesn't need to come out do not take it out.. The first thing I would do is take the carb off and clean it with some carb cleaner and pipe cleaners. Really good, you can also soak it over night in some carb cleaning solvent. Second thing would be to take the baffle hose off and see if anything falls out of the hose. The baffle is a paper element that may be bad, tell tale sign of that would be paper in the hose or baffle parts that would vibrate off without the baffle in place. That is what happened to me... If you find something in that hose it needs to come out. I don't see the baffle hose in the pic so you might have to dig around for it or you may have to remove it to get to the hose which I don't recommend doing until you try tuning it up.
Clean carb and replace carb hoses if needed.
replace air cleaner.
drain and change the oil. any oil will do. Check propane connection.
check your fuse and fire it up.
It will take some time to start because of the low pressure Propane system so give it a couple of minutes. It should start to kick over and then die, do it again and again. If it does not start completely, you cancelled out a few things with what you just did. continue to clean it up and look for more trouble. I have tons of pics of my removal if you want. Good luck.
