Hello to everyone!

I purchased my 2024 Rukus from a local dealer mid summer 2023 . Put about 50 miles on it before garage parking it on carpet for the winter. Now is spring and Rukus is super hard to start and when it will start, will not idle or wont idle for long. Pulled out old gas. Input new good quality gas. Ran it about 20 miles and it was running like a champ. Now has sat for about three weeks. Yesterday went to start it and back to hard to start and if it does, will not hold idle. If I can get it running, it will operate nicely, a bit rough here and there, as long as I keep throttle revved a bit. Would love some advise!
