Jaunroberts: Is that your 500i on a fork-mounted chainsaw carrier? I am impressed! Did you custom fabricate the saw carrier?
I built a rack for my snowmobile so I could carry the 500i, a 60 inch peavey, a gallon of gas and some bar oil during winter to remove deadfalls across the trails.
Sometimes in the summer I'll find a big deadfall across a hiking trail and I'll backpack the 500i with it's 32 inch bar to the location.
And yes, you are correct that "winter" gas usually has more volatiles to facilitate easier starting, which may contribute to some vapor lock problems. I don't know at what temperature winter blend gasoline boils compared to summer blend gas, but I have seen gas boiling in all of my chainsaw tanks, during extended cutting periods on hot summer days.
It seems the ultimate solution, is to let the saw cool down enough to start.
