I have a Coleman ct200u-ex and it has ran fine for a while and just recently it starting acting up. It would idle good for a few minutes but then cut off and if you gave it any throttle it would bog down and cut off. I replaced the carb and it started first pull and idled fine but as soon as I gave it any throttle it would bog down and cut off again. When I turn the idle up on the carb it wants to take off but as soon as the throttle is used it bogs down. Please help, thanks
