Isn't the internet a wonderful thing.
I found a chap that experienced exactly the same thing - this together with my wife's comment that the more she cranks the more smoke there is.....(no lewd comments please lol)

https://www.w-p-c.com/buggy5c.htm I quote from Ken's site:
____________________________________________________________
I had found that the engine only smoked on cranking when it did not start "with a touch of the key". If it turned over several times then it would smoke. The more it turned, the more it smoked. I had initially thought that the engine was getting too much fuel on cranking and this fuel was washing the cylinders and causing the smoke. (The smoke was blue-white indicating oil smoke, but it did have a gasoline smell). I went back to looking at this for the cause. With a little experimentation I found that if I did not pump the gas when it turned over it would not smoke. I tried out of gear, clutch not engaged, one pump, and crank. It would not smoke, however it did not crank as quickly as I wanted it to crank. I adjusted the carb to give it more choke and dropped the back the accelerator pump adjustment for less fuel. That worked better, but I developed a hesitation from the pump adjustment. The full cure is with the accelerator pump adjusted to midpoint and the choke adjusted for the current weather. I can now tap the accelerator and hit the switch and it fires right up with no smoke.
