Letting it set even if new is an iffy situation. When we have outages they are for weeks at a time especially during hurricane season. We keep three gen sets here just incase, mainly due to the lengths of time power has been out. We keep em fully fueled up with gas that has had stabilizer added to it so it does not form varnish or go stale. Trust me on this, add a good stailizor to the fuel or the gen set is gonna let yu down just when yu need it. We use a product called PRI-G, and its a long term additive. We also store gasoline and we have gas that is just as good now as the day it was purchased and some of its been around here for over 2 years time. Its protected with PRI-G....YOu can get it at most Marine and boat supply stores or buy on line or even some auto parts houses carry it. ANother product commonly available is called Stabil....its a short term additive, and what they call long term is short term by PRI-G standards......We run all three gen sets at least one time every 30-45 days with a load on them if its nothing more than a drop light or two, and we run them for about half an hour or until they are warmed up and any condensation that maya get in them is heated and evaporated, then we top em off with fresh fuel with stabilizor and they are good until the next run time. Nothing worse than having a gen set and when you need it it does not work and most times its from condensation in the fuel syste,m or the carb is gummed up with stale gas or condensation created rust and has a valve held open.........Thats one reason if you buy one even new, it can get condensation in the crankcase just from temperature changes, and cause rust......Besides your warranty period would be over before you ever used it and usually its the initial 15-20 hours most problems will show up. You need to get familiar with the gen set before yu need it as then its not the time to be reading the operating instructions, nort is depickliing an engine that was stored for a time. Hopefully by April we will have the large unit here and installed thsat has been backordered, then we can get rid of one or two of the other gen sets. The main one is a 15K automatic system that runs off propane / or gasoline. No more draggin gout extension cords and such, power gopes out, and the gen set starts and provides power all automatically. Power comes back on gen set drops offline and shuts down.......Buy one and use it, and you won't regret it. View it as cheap insurance.
