H1 carb 803 throttle lever type

[soilman]

Dear all, some help please. The above have different throttle levers on the carbs above. The one on the left is the one fitted to the car when I bought it, and the one on the right is a second-hand one I have just fitted.

The original one I has a place to put the return spring on the throttle lever, which then goes down to the manifold where there's a bracket to receive the end of the return spring.It worked well and gave a good operation to the accelerator pedal.

I have fitted the other carb and wasn't sure how to attached the throttle return spring to the throttle level as there is no obvious place to receive the spring. Then I noticed in the workshop manual the return spring attaches to a small tag on the accelerator cable trunnion and then returns to a bracket on the oil bath air filter.
I have adopted this option although I don't have a tag and have just hooked the spring over the nut on the trunnion until I can make something more satisfactory.

The only thing is the accelerator pedal doesn't operate as smoothly?

Can I adjust the throttle lever, is 90 degrees a normal position for this?

Any advice or tips for the best solution would be gratefully received?

Also another little thing that I am unsure of. The vacuum pipe from the carb is a metal pipe with a small olive which compresses. Is there another way to attach as I can't get replacement pipe with an olive? Or how do you attached the rubber versions?

I think the cable action will be smoother if you get the correct tab, looks like part 24 here: https://www.moss-europe.co.uk/shop-by-m ... 51-71.html

You can join the vacuum pipes together with any plastic piping of the correct size so that its a snug fit (mine is snug over the olive part, but not so snug over the end of the pipe so I made it airtight with self-amalgamating tape at that join)

The 'rubber pipe' which you refer to is probably this, which is just a push fit at either end: https://www.morrisminorspares.com/ignit ... rs-p831075
