I have only just got the car say maybe 2 or 3 months ago but as said had problems from the start with the Solex carbs. I have opened the top of the fuel pump and there was no filter in it ( unless I have to open the lower part of it?)   If I use the throttle on the carb it wont die not with the choke open. What happens is then after 15 seconds or so the revs begin to fade and just as you think it will cut out it revs back into life again 🤔 So am I right in thinking that if it was the fuel pump it would idle ok but as soon as you rev it ( ask for fuel) it would die? I know that the head etc is fine as it had the top end rebuilt as well. Too note that the symptoms are different with the stomberg than the that of the solex. The solex would hesitate on first pick up. Swan neck was checked cleaned etc and was working but still no good hence the conversion to a stromberg.

Moring Tony and thanks for your reply. Well I have had two Solex  carbs and the second was a New old stock and yes both were cleaned and new parts fitted to the first carb. I have read that members dont like the Solex and like the Stromberg conversion ? 🤔   I went out there again to try the car, it starts fine on the choke and will rev using the throttle leaver ( As I dont have a cable fitted as yet ? Then sort of fades the comes back to life etc. Im wondering if it could be the fuel pump????

Hi all! I have a Herald 1965 1200 with the horrible Solex carb. When I got this car the car had the electronic ignition fitted to it. So this is the story.   Car when brought was not running due to a fuel leak ( float problem ). Car would run but had very poor idle and pick up ( Just on take off). So I manage to find a new for old solex carb which made no difference to the runing what so ever! 😲 I then read about fitting a single Stromberg CD 150 carb to the car. I was unable to find an inlet manifold but found a home made jobbie that was told worked fine ( 🤔 ) With a lot of messing around I sorted of fitted but having to leave to mainfold bolts off. I have only at this time found how to wire up the choke cable. The throttle is going to be another story!!!! NOW!!!! It runs on the choke when fully open but dies if I try to shut off the choke even when hot. I have noticed a lot of black soot on the wall from the exhaust (Rich  of course as im on choke) ! I have been around with the good old break cleaner for vacuum leaks and all seems well. So short of beating it with a hammer im at a loss? Oh yes I have checked the timing!!!! I thought old cars were simple ie air/ fuel / timing????
