1934 Rover 12 SU carb rebuild
Hello I`ve just bought the rebuild kit for my carb. finished fitting it and basically set the carb up.Centered needle and set the jet so its flush with the bridge, and unscrewed the jet adjusting nut one and a half turns. I`ve refitted the carb,the engine starts quickly and next job is to get it warm and tune it up. However I noticed that the throttle control lever has no effect,as even when the knob is pulled out,it still fails to contact the arm controlling the butterfly.Should it be set so that it just touched the butterfly lever when not pulled out ,so moving the butterfly lever straight away, if it pulled.Hope the photos show what I mean,you can see it not operated and even operated it has no effect .

Hello sorry I forgot to add,is there a recommended gap between the two faces in photo 2,with the throttle knob not pulled out ?

Len,
I doubt there is a prescribed way to set up the throttle lever. Adjust it so it works with a small amount of free movement to ensure the cable pushes it fully home when not required.

I saw this post and remembered it was identical to the problem I had with my 1937 10. The levers just didn't appear to have any way of meeting up to carry out their intended function. I should say that I've had a lot of different cars with similar arrangements which usually have an obvious solution but this didn't. What I did do was to look out a hose clip of the type with the two ears and squeeze it to an oval that would go over the one lever and allow a 4ba screw to be dropped between the two levers and held by the "ear". This took up the gap between the two levers enabling a complete range of movement on the hand throttle as originally intended. No alteration has been made to an existing part so the fix is completely reversible. I shall try to attach a picture.
