[QUOTE="mcgovern61, post: 4933, member: 59"] First shot with gas back in them and they still leaked into the plenum. I opened them up again and pulled the float needles and pins. Gave them a cleaning and tested them to see if they were actually sealing. They worked fine after some cleaning. Got a better ruler and made a float gage by marking 15.5 mm on the new stainless ruler and adding a tab that was 90 degrees to 15.5 mm and then rechecked and readjusted the floats. Put the carbs on the floor, topped off the gas tank and gravity feed the carbs from the petcock. I let them sit for 48 hours and no more leaks. Turned them up 45 degrees in both directions and no more leaks. I believe that what happened originally is that between the floats not being set right, the pins not sealing correctly, the bowels became overfilled. The petcock was off but the fuel pump was still pressurized from running and with several changes in temp in the garage, the gas expanded and started leaking into the plenum. (Seems plausible to me under the circumstances :smilie_happy: ) [/QUOTE]
