411 383 Carter Carbs

[Richard Leslie Phillips]

OK - finally rebuilt the carbs with the right kit and fitted earlier today. However all is not well. The car started up instantly and then died - investigation shows the secondary set of barrels totally full, and I mean FULL, of fuel with the venturis tight shut. How is this happening? I checked the floats, swapped them round in case there was a bias in them - they seem to move freely and needles are OK. Autochoke is clearly operating as car has not had any chance to warm up so how and why is petrol getting in - the level was so high that it was pouring out of the hinges for the flaps. The accelerator pedal was not depressed at all, nor was any priming or pumping done. Where am I going wrong? Have I a linkage the wrong way round? The gaskets all look tight. Fuel flow is normal so not a high pressure thing from the pump. Clearly I have made some kind of mistake in reassembly but cannot think what. HELP! I am going quite mad trying to work it out....
