I bought a used k321 several year back, from I believe to be a good source. Just now getting it in. Pulled the head and cleaned carbon. Sanded head flat. Checked valve adjustable (good). New carb, points, coil and plug and wire. Adjust governor arm. Runs at low speed, doesn't throttle up very well. I'm at a loss at this point. Could something be wrong with the internal part of the governor, or something else.
I attached a video of me slowly bringing up the throttle. Near the end I do see gasoline spitting out of the throat of the carb, like some back pressure.
