Yeah I also questioned the fuel quality, so I put a couple cans of sea foam in the tank. Thanks for taking interest. I'll let you know if changing the fuel filter does the trick.
I have a 2018 hisun sector 750. It starts and idles fine but then stalls when press the gas. It also stalls when to press gas to go after slowing down or coming to a stop, but will start right back up and go. Any ideas what the issue can be?
