Get some new cales made up with a 90 deg or 45 deg guide at the carb end
This will allow you to route the cables in a lot smoother run.
I am not old enough to remember what the original cables looked like.
However my first A 10 had cables with curved ends.
The parts books only show the cables at the handlebar end.
Very few aftermarket cables have the angled ends on them because if they do then the generic 41" type 27 cable fits all makes & models then becomes the 54-55 specific one.

Thanks yes I have a screw on smooth adaptor on the carb, but for some reason that rubber does not sit square on it.
The air filter case determines the position of the rubber. Is the rubber still held properly in the hole in the air box? Maybe the rubber is faulty. What about the heat Insulator on the inlet?

 The airbox is the same on all plunger models,  the differing height of the barrels and choke size of the carb is accommodated by the different mouldings used for the rubber connector.

 Add the variability of pattern parts, and a few other non standard mods over time, the final fitment may require a bit of homespun lateral thinking to get a workable solution.

 My '53 plungy came with a monobloc carb, no air filter and badly scored pistons. Luckily 276 carbs, airboxes and hoses were just about easily available back in '76, as BSA dealers dumped their redundant stocks.

Swarfy.

Yes the cables are now as they should be, so thank you all. I just have some work to do on the filter rubber, maybe to shim the air filter so the rubber moves to the right a bit and centralises the holes.

i ended up gluing the rubber hose onto the air filter carrier box - not strong glue you understand! This prevented the rubber from detaching from the air filter every time I tried to mount the carb. Now both are attached as they should be, so I hope this helps you  *smile*

Thanks Russ, yes mine is the angled one it just does not line up, but I f I shim the air filter with some packing washers it should, it just needs to go right a bit more. Thanks
