Hello all, My son's 2017 110 EFI started to become harder and harder to start. Once started seems to run fine for the most part. It seems to be flooding out at start up as you can smell gas heavily at the exhaust. Would a dirty injector cause this issue if it were stuck open? Has good spark and new plug. Plug is wet when I pull it after trying to start. Also it doesn't seem to not be "sucking" air at the intake, maybe I'm just use to carbureted models.
