I'm currently cleaning up my set of spare carbs for my 400 and have found a part I never noticed previously.
There are two solid dowels between the carb pairs - can't find it in the parts book - anyone know the part number please?
-
Ted, are you referring to the short peg that the throttle return spring hooks on? If so I don’t think there is a part no?
-
It was never available mate, i have a box of assorted 400 bits and will look on saturday for you but dont know if there is one. I think the 500 is same part.

Its not that part it is a dowel that sits between carbs 1-2 & 3-4 towards the rear of the body - some sort of alignment spacer. One of mine is missing. TBH I don't think the carbs on my 400 have either of them.

If you happen to have one brilliant - thanks Bryan.
Update:- It appears there are plenty of Dowels on flea-bay in SS 10 mm x 6mm reasonably cheap - just plain with no center groove. If I can find an original would be better.

Ted, is it possible to photo this area? I'm rebuilding a set and don't seem to remember seeing them before they were stripped....
-
quick find,
type in CMSNL CB400F Carb and look at part number 17 which is the spring Matt, I think Ted means the bit that sits at the bottom of it to attatch the spring to, I had nothing else on my carbs when I dod those. Cabt really think of anything else that refers to a small round connector either........

He reckons not in an earlier post.

MOrning Phil,
dunno what else it can be, Ted you described it as a barrel of steel 10mm x 6mm with a groove in it, there is only one, I'm sure.
Could we employ the use of a 400 anorak please?......anyone?
-
Having stripped and rebuilt my 400 carbs last week the only thing I can think of is the spring peg between 2&3. As had been said it is in the parts book diagram but doesn’t have a part number and there’s only one of ‘em. If it’s not that component I’m mystified.
-
I like the way you came forward as an anorak Tim ;D
Arent you supposed to be doing your 1 day a week today and working?

OK, when this sodding rain stops, I'm off to the shed to 'ave a shufty!

Yes thank you Roo. Up bright and early for my Cardiff gig.
It’s a bit damp over here so the anorak has come in useful.

OOOsh, a wet Cardiff.......nasty! ;D

Ooops, bout that ;D ;D

On reflection I think the suggestions about where the spring sits accounts for why I only have one dowel - that's logical - it explains the groove as well thanks Philip, Multiman & Mr Spock . My Bad.
As a poor excuse I dismantled, numbered & individually boxed the parts about 5 months ago just started assembly last week. Currently using the US cleaner for each carb as I put them together.Duh
-
So is the spring dowel missing or not Ted? If you thought there were 3 of them I can see why you'd think 2 have gone missing but are you still missing the original between 2 and 3. TBH it looks to be the same part as the 500/550 carbs.

I have just the one - it's the center spring dowel - so all is well.
-
That’s the chap,Ted. Short solid barrel, waisted in the middle for the spring👍 The item below ‘17’ on the CMNSL fiche as identified by Roo.

Yer welcome 8)
I got summut right for a change, get me ;D ;D ;D
-
👍👍👍
-
Just found mine - so thanks for the heads up as it would have been a pain to take 'em all apart again....

-
Yes that's the part!
-
Mine are now all back together - now comes the fun part of setting them up!
-
You still thinking on bobbing over to have a gander at the 400 engine this week Matt?
-
Actually, tomorrow is free - OK? PM me details....

I clearly have the memory of a Goldfish when it comes to putting my carbs back in place on the manifold/frame.
Is it correct to set the height of the sliders using the screws in the picture below to adjust them as needed - last time I used a small drill bit shaft iirc.

Yes, those are the screws to set the slider heights.
-
Thanks I just can't remember using them when I first rebuilt the carbs on my 400 before Covid - in my head I thought I used the screws between the carb links.
One of the float pillar tips was in poor condition so this spare set will eventually replace them. Keeping busy tinkering before I resume work on the 500 forks.
-
Just assembled the four carbs onto the manifold - all has gone okay.
The locking taps that fits between the pairs of carbs are missing on my spare set so currently trying Steve at 400 bits for a pair so I can crack on with float levels & bench synch etc.
