The clutch dog is slipping which is a sign either it or the shoulder on the inner hub of the gear is worn., the “sneeze” is actually the gear quickly disengaging then catching again as the parts rotate. You might be able to fix it by flipping the gears around from front to back. You’ll have to disassemble the lower unit to find out.
To be honest, your motor doesn’t even SOUND good in the video, it almost sounds to me like its only running on one cylinder. Maybe its just how the camera makes it sound. At any rate, what I see is that the white smoke isn’t really coming from under the mag plate, its exhaust smoke/steam being recirculated from the back to the front. Maybe there’s a leaky hose or or seal or fitting somewhere, because either there’s an air leak or the mixture needle needs to be fattened up a little. Just my deux centavos.

He's livin' in his own private Idaho..... I hope to go out quietly in my sleep, like my grand-dad did..... and not screaming, like the passengers in his car...
