No, none at all. In fact, one thing that has always impressed me is the way it fires up instantly, regardless of weather. In the fall of the year, I drive it up until they salt the roads, so it gets driven in temperatures approaching freezing. This may have a little to do with the fact the Strombergs are old & worn, and running a bit rich in low speed operation. That may change when I fit a fresh set of carbs next summer. A (different) fresh set I had temporarily fitted last year showed no starting issues, though were only used in warm weather.
