Ignition timing cable routing

[AMC Tommy]

Hello,

I'm a mechanic and Ive just joined the club. I've also recently purchased my first vintage bike/ AJS M30.
I am quickly learning about whitworth and BSC threads and slowly working through all its little issues, but it is a 'wellish' preserved bike and has had some love before it came into my hands.

My first question for the AMC gurus, is about routing of the ignition advance/retard cable.
Somebody has filed a groove into the intake manifold to take a bit of the bend out of the cable.
Can anyone tell me if this cable is supposed to be routed between the intake ports/centre of the intake manifold ?? See attached pic for current routing.

Thankyou!

One way to tidy up issues like this, its common on throttle cables too, is to adapt the "noodle" off a bicycle brake. They are cheap and you can cut and adapt one to fit. A lot of Japanese bike have angled cable tubes on carbs and you can modify one of those.

Hi Tommy, I run my cable inside the carb manifold and curse every time I have to fit the mag, there is very little room there especially if the cable adjuster is wound out, one of the disadvantages of a compact design.

Thanks for the noodles idea Limeyrob. I would never have thought of that.

Duncan, thanks for that. That may explain why they ran the cable on the outside then. Good to know
