Hi, car died the otherday... had AA out , and it seems my mechanical fuel pump on my 998cc a+ is not cone up tightly .... and wasn't engaging with the cam.
So obviously want to tighten it up , but despite removing the twin pancake gilters on my twin carbs, I still can't get my hand to the bolts.
Whats the easiest way of getting to them- can I just remove the inlet qnd twin carbs as a single unit ? I can see two long brass nuts which look like they might be what holds it on ..?

I've always been able to get to them with some difficulty but I do only have a single carb. A ratchet ring spanner is super-useful here. The reason they're loose is probably because the last person couldn't get a good hold of them!
Probably easier to remove the carbs than the whole inlet, which possibly takes the exhaust manifold with it (can't remember). If so you would have to tackle the clamp at the flange which is also a devil to reach.

if you can disconnect the engine steady and gently jack under the back of the gearbox to tilt the engine forward it may give you just enough room to get to the bolts

looks like inlet is separate from exhaust manifold - I have a LCB

Remove the Twin SU's as a unit with the inlet manifold as in photo above.
The two long brass nuts are to make it easier than standard nuts to undo and reach in with a spanner or socket to release the inlet manifold, leaving the exhaust manifold in place.
Hopefully you won't need to replace the manifold gasket otherwise you will also have to disturb the exhaust manifold...

grrr... its the heat shiled - can't get anyhting around it .... going to have to invest in a 1/2 rachet spanner
..is NOT a girl!

How about having a go from underneath?

so I failed to get a spanner around the nuts- even my rachet spanner was too thick so I removed the bar that the carb springs attach too
see photo...
.... which I should have looked at before lol
https://www.minispor...rsion-9463.html
lools like I have put mine back upside down -so the springs will have less tension..... so I guess I'll be taking them off again.
First attempt I managed to drop the small bolt , and its lodged in my subrframe or somewhere - so had to go to halfords to get a suitable replacement.
Have also since learnt from the pic of the cooper kit, that those brass nut thinhs have a hex hole in them , so probably could have got them off with an allen key or hex drive ...... grrr
Anyway - fuel pump is now nice and tight for now..., will keep an eye on it , and if iit works loose again I'll have to bite the bullet and put a new spacer gasket etc on.
Anyway ... now back to trying to sort out the mixture and balance the blighters

remove carb springs first then i had a cut down 1/2 inch ring spanner to get to bolts underneath inlet manifold and remove the lot, one reason i went back to single carb. then pump not too bad. you may not want to hear this but hope you put locking washers on pump bolts. restored other halfs and forgot these, they came loose causing oil leak and yellow van of shame on first major run. even harder on hot engine

I didn't check - as I just tightened what was loose.... then afterwards thought .... maybe there wern't any ..... though there should be as the whole engine was rebuilt includinfg new fuel pump by a certain well known northern mini specialist a mere 4000 miles ago ........
