This is my first post so sorry in advance, I suck

Ran stabilizer through the Ruckus before packing it up for the winter. Changed the belt to a Polini belt. After the winter, took it out of storage and it would run, but would eventually bog down and die after a few minutes. Figured the carb was gunked up so I took it apart, cleaned it, put it back together. Siphoned the old gas and put in new, did an oil change, replaced the fuel filter and fuel pump, new battery.

It ran good for three days and now I'm back to it running and dying. Half the time it won't even start up. It has only a little over 300 miles on it so I'm not sure what the issue is, only things left I can think of is the spark plug and air filter, currently waiting for those in the mail.

Not sure what else to check. Anyone else run into this issue?
