But on a very cold winters day etc...
I always let my old carbed subarus time to warm up.
They get carby freeze badly in the cold. Since the carb/carbs are quite a distance away from the block.
If I jump straight in and take off it can stall at a intersection etc and take a bit to get it started :
If I warm it up then I dont seem to stall, and if I do I can get it started right away
