Hi, new here, but hoping someone can point me in the right direction because my dealer said that they are about 2 weeks out for service. My 2021 HPX (only 45 hours driven purely around yard) all the sudden started backfiring and running real sluggish. I changed oil, new oil filter, new air filter, and new fuel filter, but still same issue. The engine will rev perfectly fine parked, but as soon as you start driving it will only go like 2 mob and eventually dies. Even after idling for 1 hour it does as soon as choke pushed in. Any ideas for problem solving? 93 octane gas is in it, but has Stabil in it and not old at all. I found this clear tube coming off of carburator, but can't figure out where it would attach to. Should it be hanging loose like this? Thanks in advance for any advice!!
