Hi Ric,

 

From the manual: 

 

Engine cold start smoke

 

Igniting the engine in a cold environment may cause a condensation vapor cloud to occur when the temperature is below -5*C (23*F). The colder it gets, the more the effect will show.

Hi Ric,

 

From the manual: 

Manual, what manual? Oh found it, it's the little "i" on the "Modify/Install" bar. :P  Thanks for the quick reply, I new it was temperature dependent, just not what temp.
