Hi, im new here and trying to figure out why my CT200UEX has a running at full throttle issue. Everytime I give it full throttle it keeps sputtering and won’t clear up. If I let off just a bit, it’s fine, but like I said at full throttle it is sputtering. It’s fairly new with only about 15 to 20 hours on it. Fuel is clean, carb bowl is clean also. The only mod I did was removing the throttle stop. The spark plug looks good as well. I thought maybe it was valve float, but I installed 18lb springs and it still does it.
Does anyone have any ideas of what is going on?
