I'm with Bob K with no priming system at all. And it gets cold and snowy during those winters in northern Utah. A touch of pre-heat and 2 pumps on the throttle then crank it over. Starts on the 2nd blade every time. My RV6 bud's primer line broke just after the pump (forgot the service loop). He pinched off the tube and ran without the primer for a couple of months and never noticed anything different during engine start.
You'll also be flying sooner.
