Sorry i can't be of any true help, but once it is set up properly it should start and run smoothly at any temps. Mine has cold started from -7 through to over 40 and starts first go and runs factory smooth straight away. But I had someone tune mine for me.
Do a google search and some of the microtech manuals should come up, I downloaded one over a year ago for an MTX and handset, but can't remember the site now.
Good luck with it.
I am sure someone on here will offer some useful advice when they read this post.
