Ok..... cleaned the carb good and adjusted the air/fuel screw and tried it. It idles pretty good but I did find some rust in the tank from the fuel cap, gonna drain the tank and wash it out and put new gas in it and try to see what happens. So , for now it's possibly fixed . Didn't let it run long so it wouldn't suck the rust in the carb. Will know for sure tomorrow Sent from my SM-G950U using Tapatalk
