Just got our electric bill that includes temperatures during the period. In the month up to yesterday the high was +6F and the low -41F, average -11F. My RTV900XT, which has Howes, wouldn't start on the coldest days. This week we had our +6F day and it wouldn't start due to cold soak. The next day at -4F it started right up but it hadn't been below -10F during the night. The fuel tank is a large temperature sink that takes time to warm up. My L6060 sits in a heated garage as its needed to keep our yard and driveway open (1/4 mile) so never a problem there.
At -41F I would refuse to start too
How warm do you have to keep your garage for the 6060 to start in those temps?
