That may mean a bit of work to get it going.

If you didn't add stabilizer and run it enough to get it into the carbs, or drain the floatbowls (best), then you probably have a tank of bad gas.

Left sitting long enough in the carbs, the gas will evaporate and leave a film of "varnish" in the bowl and jets. If it's bad enough you'll need to remove and completely disassemble the carbs to remove it.

Start by charging the battery and draining the floatbowls. The gas that sits there loses volatility and goes bad the quickest - making starting difficult.

Draining the tank completely and filling with fresh gas and stabilizer is a good next step. A full tank of stabilized ethanol-free gas will last a long time, but draining the floatbowls while it's in storage is always the best imo.
