Got a second hand B70 (?) Keurig from a friend. It didn't even flow water until I slapped it around and freed up a stuck servo. Now it flows so well that it blows right through the k-pod and doesnt even get the outboard grinds wet in the used pod when I opened it up. Is there a duty cycle servo that limits the flow to the pod so it gives it a little more time in the grounds? It literally dispenses brown coffee for about 10 seconds then the water coming out looks like water for the next 30 seconds. Wth? Using a med/dark roast pod on 10oz setting, dont want to use the "2 pods on 6oz" trick as that defeats the purpose. Could I put a restriction on the feed like a carb jet?
