I think given descriptions of what you are experiencing, we can talk you through this and soon you'll be up and running. These things are pretty bulletproof and most issues turn out to be a shorted wire etc, nothing drastic.
Longer term if nothing helps, I see you are in Yucaipa. Someplace around there (Apple Valley? Corona?) there is an importer of VN Refurb Yanmars who would have a mechanic competent to work on your unit. Look in Craigslist and you'll see him, he advertises a lot. But I'll bet he just shows you a seat or clutch safety switch, a chafed wire or air in the fuel lines etc, something you could troubleshoot yourself after you have some experience. Don't bother looking for help locally until the group here has talked you through the likely stuff.
And Welcome!
