Come to think of it, there are always the California wackos. i read once that Zero Turners in CA have a charcoal canister somewhere in their fuel system, whereas the other 49 states don't. I know my RZT doesn't have one. On my diagram the purge line comes from the fuel pump and goes to the frame of the air filter housing meaning whatever comes out of that purge line gets sucked back into the carb. That's starting to make sense. Any thoughts on my other 2 questions?

This is more than "just needs a starter". If you are a mower mechanic, this would be a great deal even if it needed an engine replaced.
But, if you are a DIY novice with limited experience, let it go.
Yeah - I thought about the possibility that CA would be a special case (evap system). Perhaps the Honda aftermarket sells only the 4-line pump to simplify their inventory system (one less part number and part manufacturing/sourcing variation that has to be managed) - perhaps the 4-line pump is universal application by just capping off that line if not needed? (But probably not a good idea to just assume that.)
No ideas on your other two questions. Were you able to find the wiring diagram? A wiring diagram might explain the mystery switch/oil pressure sensor/whatever.
Hopefully someone comes along that is familiar with your particular mowchine.
Peva, actually the 4 legged fuel pump is the original one OEM and I am sure that's all Honda installs just to keep it simple, regardless if the mower goes to CA or AL. They probably just do the line routing a little different to bypass unused features and that's what I am trying to get a handle on. I got everything basically sorted out except for that mystery line going to or coming from the carburetor and that oil switch (maybe it's wireless LOL). I got some half ass wiring diagram which is very difficult to make out but I will try again
I found a great shop manual and I found the answers to my questions. That hose 30 (in post #29) coming from the carburetor is nothing more than a drain hose. The nearly 2 feet of it just hang there open ended pointing to the ground under the engine and allows you to drain the carburetor before removing it and the oil pressure sensor has no wire connected to it, believe it or not.
Well here it is, ladies and gentlemen. My beautiful, practically restored 2017 RZT Mower, running like on day one. I got it for $250 and spent another $435 in parts to get it all in shape, mostly cleaning it up thoroughly, checking everything out and putting it back to factory specs. Most of the parts money went to replacing all the missing shroud covers, which I had to buy new from Honda. I couldn't find anything on ebay. So what was so terribly wrong with it that the previous owner threw in the towel. Poor guy, no matter what he tried, the mower was dead and stayed dead for a good reason. It had a bad ignition module and a frozen starter. After I replaced the starter it still was dead. The next step was the ignition module which did not pass the test. After replacing it, the engine cranked and I knew then, that the problem was licked. Everything after that was easy putting this jewel in the rough back together. This project is finished and ready to be put into action come spring time. Thanks for all your help, ideas and suggestions. For your enjoyment I have attached some pictures and a video. Nix the video. The forum says it's too large and I don't know what the limit is.
