Thanks to everyone.
So I do not see how that could be the problem with motor not starting when cold.
problem with the thermal heater would be a problem with it running too rich after warm up

the carbs for a two or 4 stroke work identically.
it uses a colum of air that at se*****l is about 14 miles high.
pulse pumps work on both two and fourstroke engines.
they have been around for years.
most large 4 stroke motors use another carb circuit called an accelerator circuit that most two strokes do not need.

Is the prime start any different (basic operation) between the 2 and 4 stroke?
I would think just the volumne of air going thru ANY carb(cranking), (2 or 4 stroke), with the prime start "activated" would allow extra fuel to be sucked in
Just an educated guess...
