I just got my new 914 running. On my second flight after landing and taxiing in the engine started running rough. When I tried to add throttle no response. When I pulled it back to idle it quit. I got out and found some fuel dripping out of the back of the cowling. I let it sit a minute then tried to start it with the fuel pumps off. After a couple tries it started and I was able to taxi back to my hangar. These are brand new carbs. Before I installed the carbs I checked the floats for proper weight and they were right on spec. Wonder why they flooded out after landing?
