Dellorto Carburator

PostPost by: pete.chiswell » Thu Aug 19, 2021 1:26 pm

Hi I have +2 130s which came mainly in boxes. I have assembled the pair of Dellorto carburettors, no bits left but I cannot see how to connect the throttle cable to the carb. I have a barrel nipple that fits the inner cable and throttle linkage but no way of attaching the outer cable. I have no bracket nor can I see any screw holes. Can anyone send me a picture of how its fitted or part numbers. I attach a photo of what I have.

George, pardon me for adding to your post.

Pete, It is an odd arrangement.
The inner cable is fixed to the air box bracket with a nipple as you would see on a pushbike and in George`s photo but does not move.
The cable arrives at the carbs from above and the outer fits into a barrel nipple on the shaft lever.
It is the outer cable which goes down and up to open and close the throttle. It was an unfamiliar method to me and not obvious at first, but it works well enough.
Mine has Weber carbs but I think they use the same arrangement as yours.
Hope this helps

When you do put it all together, make sure the accelerator pedal does fully open the butterflies on the carburettors. Mine used to be a real so and so to start then I discovered the accelerator pedal was not opening the butterflies fully and as such was not operating the accelerator pump which supplies a richer mixture when starting and accelerating hard. (I don't use the choke control, just 3 pumps on the accelerator pump by flooring the accelerator pedal 3 times before a cold start).
