Choke Cable Route and P Clip


Recommended Posts

Fitting the carburettors this afternoon. The choke cable seems to be about 2 inches too long. Does this mean I've chosen a shorter route? Does anyone have a photo or a description of the route from the dash board to the grommet through the bulkhead. Also along my route I can't see how how the "P" clip as per the Moss catalogue can attach it to the bulkhead.

Any advice before I shorten the cable would be much appreciated.

Cheers

Jim

Hi Jim ~

 

Here is a photo of the choke cable run on my 3A. I am able to operate the choke easily with

my left hand.

Tip ~ Connect the cable to the carburettor trunnion pin and lock the cable in position then

remove the cable and trunnion from the operating arm and rotate the trunnion two or three

right hand turns and reconnect to the arm.

 

This will make the choke knob spring into the locked position on the dashboard.

+1 Good tip Tom, I do this also. If you don't then the knob will always work it's way back in.

It is also worth checking that the spring clip, & the thin brass "pawl" are present , & working properly.

It may be worth filing the ratchet teeth to make them more positive.

In the old days, a 'ha'penny' was all that was required

to get started.- wedged under the knob.

 

But since ha'pennies are hard to come by these days,

(and could cost a dollar these days) twisting the cable

a few turns works a treat.

Thanks Tom et al,

Nice picture Tom. That is the way I have it coming through the bulkhead on the engine side. Nice and straight. I am wondering about the dash board side. I ran it in a straight line out through the grommet but just wondering if I'm missing something as I can't see where I could possibly use a "P" clip on the cable. Can anyone tell me where they have a clip?

Cheers

Jim

Another important point is the correct functioning of the choke control.

 

On the pull to the first notch on the control this should only open the butterflies sufficiently

to increase the fast running ~ it should not lower the jets.

 

The second notch setting should then lower the jets.

On my 3A I moved the choke cable to a new position on the dash board near the speedo. Now it does not have to bend around the heater and works much more smoothly. I have the Standard Triumph wooden clothes peg which will hold the choke once fully pulled pulled out.

 

The original choke knob has been replaced with the spot lamp switch. It all looks OK.

Don't forget that the cork sealing washers on the carburettor jets harden and shrink which also

makes the choke mechanism extremely heavy to work.

I replaced my cork washers with neoprene 'O' rings which made the choke much easier to work.

I soaked the 'O' rings in a mixture of oil and petrol for a few weeks to see if they deteriorated

but they withstood the test.

I have HS6 carbs. My choke cable is attached to the front carb. Does it make any difference - front or back. Reason I ask is that I have rough running on cold start up - won't run properly until it is hot. Carbs have been tuned albeit when engine hot. Have tried full choke , half choke and is very frustrating especially when having to rev hard at lights and then bunny hopping through them.

Regards

Brian
