Man I hear ya, I still got one of them small fishing tackle box’s filled with jets and the all essential handy dandy jet tool that I always take to the track. The jet thing is what finally drove me to make the swap to EFI on race car. When I moved up here to Fargo the temperature swings on race day were nuts, it was nothing to have 40 degree swings over course of the day. For the record I am simply not a super carb guy tuner! Long story short I pussed out and went EFI. Oh yeah super repeatable and she starts every time. I gave a super nice race carb that was polished and worked to the point of being art to one of our FABO members for a hot dog and a beer at next race! Long live EFI
