Stripped down the monobloc carb and put it through my ultrasonic cleaner, only a small one with a 50w power output so I didnt hold out much hope of success, but it appears to have turned out well. The proof will be when I try to start it, soon I hope. The brucie bonus was that I had no parts left over when I had finished, which is always a bonus with me :? :? .

Just noticed on the 3rd pic that I fitted a gasket below the fuel filter, and having just read the CB article on Amal Monos apparently its a common mistake to make (one gasket left over which fits directly onto the fuel filter) so off that will come next time out

Well I finished the front end rebuild, and set about fitting the new clutch plates and pushrod.......
Offered up the first plate and it was about 1/2" too big

and the auld one sitting on top

The new pushrod was also about 1/4" bigger but matched the size quoted in the manual, so only one conclusion, The clutch, which has been adapted to accept a belt drive, is not from a Triumph. I spoke with the guy from Wilemans who reckons it may be from a BSA, possibly b40.
Any ideas anyone

Well b40 it was, and a new set arrived today. I now have a full set of 5Ta friction and plain plates to sell on fleabay.
Anyway onto the clutch cable. I have to remove the gearbox outer casing held on by 4 allen screws and 2 x 1/4BSW nuts. Not I dont have a huge supply of WW tools but my 1/4 ring spanner wont fit as it is tightly recessed into the casing and the 1/4 socket will only fit around the rear nut.....so to Zunspec, or indeed any others with firsthand knowledge, what did you use to remove the fwd nut.

Hi jimmy,

I used a Whitworth socket which fitted for me. I will go and check and take a photo though.

Cheers Geoff

Hi jimmy,

Seems that I use a 3/16 Whitworth, fits well on the nuts I have.

Mines is deffo 1/4 (just went out and tried it)
I can get the socket over the rear nut, but with the recess in the casing, the socket wont fit on the front nut, but hey ho, I'll get it someway. Bit of a bummer having to remove casings just to fit a clutch cable eh?

Hi jimmy,

The conundrum of all the disparate imperial sizes used by Triumph still confuses me :D . I ordered these nuts by Part Number and I think they are 1/4 thingy but the 3/16 Whit seems to fit. Helps as there is a good "necking" on that socket.

Cheers Geoff

Jimmy, I needed to "adapt" a socket for my old B25SS doe to the bolt head being in a recess.

A grinding disc on my drill in a vice and using an extension bar to mount the socket while I ground it did the trick.

Another time I was able to get a box-spanner in where a socket wouldn't fit.

Maybe try grinding off some metal around the socket's business end?
Just being old doesn't make it a "Classic."

Aaaah! Nostalgia is not what it used to be!
