Wow! I'm surprised at the results so far. vast majority run without a choke. I've never had a car that didn't have at least a manual choke but I get the pump three times and ride the idle warm up deal. For as little as my car will be driven, and in relatively good weather, it sounds like I'll be fine! One thing about the inland NW, guys with nice cars can't break them out until may or june because there's so much traction sand (more like gravel) on the road that it's nasty on paint.
