Last thing you want is a snowblower that becomes hard to start when it's cold out.
You make an interesting point. I have two Honda GCV160 machines and two Chonda powered machines, including a snow blower, and all take the BPR6ES or equivalent Iridium BPR6EIX. The cooler F7RTC doesn't seem to make sense for this application. Cooler plugs are used for higher compression or turbo boosted motors, which isn't the case here.
That being said, the OP should give this machine a serious workout with the factory plug, then inspect it before changing the heat range.
