Ok so I kept those carbies with the fuel turned on for 24 hours and they all held fine. Now I have 2 on test that were in my reject needle container, 2 new primer caps and gave the seats a polish with the Autosol. One leaked fairly quickly so I polished it again and now it is holding so I will leave them on test for the next 24 hours. Hopefully they will pass the test. Seems the only way I can sort these out
