2T-G Solex - Choke Cable?

[sillycar chick]

My solexes need a choke cable obviously, but what can I use? I have thought of using one from a KE55 rolla, as my old one used to have a cable setup through the firewall to a pull switch on the dash, but I just cant find one right now.

Anyone know of what cars have suitable choke cables to retrofit to my '22? Rodger the solex freak, surely you do? I know its a pretty simple setup, but just trying to make things easy and look fairly factory.

Sillycar Chick,

Any of the after market choke cables that have the steel spring like outer, and a solid wire inner.

Pull out the inner and cut the outer to reach from the dash mounting into the enginebay. Your rear Solex has the outer clamp mounted closest to the firewall.

Depending on which choke tops you have there maybe a bar missing that clips into both choke levers. If the bar is there, then the inner gets screwed under the rear choke lever sloted bolt and screw. Cannot see enough in your previously posted pics.

If both choke levers have the sloted bolt and screw then lay the inner wire across into both slots on the Solexes.

If the front Solex does not have a choke lever like the rear, then let me know as I can exchange you one.

All that said. I have found that once the Solexes are set up I never use the chokes even in the depths of a Canberra winter.

It all comes down to the starting technique. If you have time to sit and hold the revs at around 1200-1300 for a minute or two then it should idle from there and drive just fine without the chokes.

Rodger, thanks for all the info. The inner and outer cable you are suggesting I am assuming is the same sort you see on your lawn mower. There is rolls of this stuff at my dads leftover from the mower shop we used to own. But the lever would be the tough bit.

The carbs I have both have chokes on each side. I will try to get you a photo tonight its hard to expalin how they work. But it seems to be they style where you would have a cable run through both and screwed down.

The car doesnt start without choke when cold, and starts very easily when choke is used. However, it still has to go on the dyno to get the carbies checked out, there are a few flat spots and I am suspicious they are running lean.... Dont know if this would change cold-start conditions when they are tuned up properly?

My 2TG i only just recently got running right, there is no flat spot and it will start without choke when cold (2 pumps of the throttle, then hit the starter normally does it)

Just pulling ur jets and blowing them out will do them wonders if theres something lodged in them

The aftermarket choke cables have the knob and fittings to go straight into the dash location just as the old one did.

Just spent 20min "googling" for a picture. No Luck.

It is a bit of a technique to start them when cold without using the choke, but it goes a bit like this.

1) Pump the throttle two or three times to suirt raw fuel into the motor intake.

2) Start cranking the motor and pump lightly several times as it fires up.

These are the steps that replace the choke actuation and provide the richer mixture for cold start.

3) Hold the motor at 1200-1300 and maybe give a couple of light pumps to get it through the first few coughs and splutters.

4) When the engine holds a steady idle at this speed hold it for another minute or two and then it should run at normal idle.

A lot of times I can count the four cylinders "pop" one after another "1....2....3....4", the motor clears and it then runs smooth.

If I seem to be providing too much information then I am doing so to also help anothers who maybe reading.

Appologies if I am teaching how to "suck eggs" so to speak.

hmm... if the cylinders pop 1...2...3...4 then you have a timing problem or unusual cams and crank rodger. they should pop 1...3...4...2

Cheers, Owen

Ok, Ok

Stricly speaking in firing order, maybe, but I dont tend to be looking in the enginebay at the time and have not yet tuned my ears to distinguish if they do go any order.

Doubt there is crap in the jets, they were rebuilt not long before they were stored in a box for the past 20ish years, however I know my dad was running slightly leaner jets in them as he had higher octane fuel or something..... I think a good tune-up and slightly bigger jets will do it good, but I cant get the car to the dyno until I get my guages working again...

Ahhhh, makes sence

to the best of my knowledge mine havent been touched

If there was fuel in the carbs when stored, even small amounts in the jets etc, then the fuel could have crystallized and cause blockages. Well worth getting to the jets with clean r carb or similar and be safer than sorry.
