Hello, We just got a model four-1200 kit about 80% completed no engine mount yet but firewall is installed. It came with a new never run although 20 plus year old Rotax 582.
Couple questions:

How does the 2 stroke handle the temps in Alaska?

Should this engine be torn down and check because of its age or should it be good to go as is? It's never been ran or even completely assembled.

What about the Rotax Rick 670 conversion? Any good? 100 pound 92 horse engine sounds pretty good.

And what is a good engine monitor set up for the 582? Or is it better to use individual gauges?

Thanks I'll know more about exactly what i have when I get it home Wednesday.
