Well seeing how you didn't leave a year or a model number , we would all be taking shots in the dark on this one.

A model number would really help.
I would guess that the smoke came from the shift switch in the control box, maybe a shorted reverse shift wire somewhere.
Not having full power, spark, compression fuel delivery. What's your compression? Have you checked spark, bright blue, plugs in good shape? How long since the carb was overhauled, getting fuel to carb?

Your symptoms are too vague. Nobody can diagnose it from such limited information. Somebody with a bit of knowledge about motors is going to have to do some basic troubleshooting on site.

Electrical mechanical shift...this is why I don't work on anything older than I am approx. All I know about these models is that the entire gearcase is considered ground and that you have to use the Hi Vis gearcase oil.
