Hi, Car was running rough and when turned off petrol syphons into venturi so:-
Replaced all the jets and diaphragms with a full carb kit, tried to set it up with a colour tune.
Unable to get a blue flame constant yellow runs lumpy. stripped down again found nowt. Checked in various manuals (Ford,intereurope and Haynes) my carb appears to be different. there is no anti syphon valve (carb body isnt even tapped to take one and below the discharge jet there is what appears to be a captive spring and ball)
Timing ok, electronic ignition no points to worry about. Tried a friends carb ran ok. :?: Any ideas please :?:
Thank you ScruffyOctober 28, 2010 at 11:13 am #24444October 28, 2010 at 12:01 pm #24445
Not really. To diagnose problems such as this, you need to be there, conduct tests and see what the results are. Then you apply corrections and test again. It isn’t always possible to do this at one remove, depending on limited information provided by a third party; all you can do is take guesses.
You need to find someone who can carry out the diagnosis on the vehicle at first hand.October 28, 2010 at 12:19 pm #24446
I will re check it all again, it is the lack anti syphon jet and the body not being threaded to take one also the captive spring and ball below therubber seal and discharge nozzle is this a later modification?

What year is the car? Could you paot some photos of the carb to check the actual type? The anti-syphon system was part of the accelerator pump. Early carbs didn’t have one.October 31, 2010 at 12:40 pm #24461
here are the photos you asked for Jan.The car is a 1966 super,
Hope the photos are OK.November 2, 2010 at 1:32 am #24474
Solex PSE type carbs that I’m familar with are the 30 PSE-12 . These were common on the Ford 1198cc engines.
These had a anti-siphon valve with an floating ball ( illustrated in the Autopress workshop manual on pg 35. ) No other shop manual nor Ford parts manual shows the ball and no part #.
The ball is usually lost after rebuilding the carb causing the carb to flood.
Try removing the spring and let the ball float as intended on later Autolite carb for the 1200. The ball is shown in the Anglia parts list as p/n 370920-S
