I have rebuilt many Zeniths carbs. this one has me. After I rebuild them I test them on my original 31 model A. I bolted it on, turned the fuel on and in about 3 seconds she floods gas out without even starting, leaks when running also. I changed the float valve to a new one that does not leak, checked the float level, float good with no leaks, gaskets good, checked all passages, checked GAV, checked jets, filled bottom half when apart and did not leak, assembled it and leaked. float valve looks to be seating with float . Had it off and on about 8 times. Need advice.....Thanks JD
