clogged carb?

[dwint51]

I have a 2t with only 469 miles on it.i put sta-bil in it before the winter and started it the other day no problem.it smoked like crazy but ran fine.i go to start it yesterday and nothing.i took the gas line off at the filter and it was clogged so I blew it out and when cranking the gas is coming out good.when I connected it still nothing.i took the plug out and put carb cleaner in the head and it started for a few seconds.my guess is clogged jets but would like some advice please
