I (still) think the problem would be easier to identify once the butterfly mechanism is freed up. Early on in the video the gap between the follower and the cam is clearly visible when the cam is moved toward ‘fast’. With the follower in the upright position, the butterfly valve is nearly closed, so the engine is in effect trying to run under full choke, which may at least account for some of the voluminous smoke..
