Choke issues on type 4 engine

My 2L type 4 with standard carbs, appears to have lost the choke. ..as in depressing throttle to floor, no longer makes engine revs higher when starting from cold.
I presumed it was a mechanical action that set the choke, so may be just cable adjustment. ...unless someone knows different !
With colder weather loomin

 

Will have a look tomorrow.
Thought just a tug on a cable was too easy ! Thanks for reply.

 

The choke works on a heated coil

 

That wire runs from the coil so maybe trace it that way too.

Could this be an accelerator cable/throttle linkage issue?

I'm no expert mechanic btw.

 

Recently changed coil, so may have dislodged a wire.

 

If there the standard solexs you should have 3 spade conectors on the left barb and 2 on the right !! The choke will be facing u round with spade connectors they can brake off quite easy !! Should all be connected to the + side of the coil

 

All connections are in place and in good condition.
The wires look like they were renewed when carbs were refurbished about a year ago and it is a new coil, so everything looks lovely and is attached. ....doesn't mean that it works though !
Are there replaceable parts within the carb bodies ?

 

Just been reading Haynes. ...it says bi metallic strip opens to activate choke " after a minute or so " , so perhaps I am rushing start up procedure.?

 

I believe (perhaps incorrectly) that slowly depressing the clutch locks the chokes closed, and then they open slowly after start up as the element heats...?

 

I've really got a problem then..................mine's an Auto !!

 

Wrong

Correct

 

The choke cam that speeds up the tickover is operated by a dab on the pedal, then slowly comes off (or in jumps really) as the elc element warms up, also turning the choke flap. On your T4 carbs, there is a linkage outside each carb with two little locknuts (M4?) I expect one fell off a long time ago and now the other has. Even with just one operating the revs will increase.

 

Thanks Zed....so I'm looking for missing locknuts...or rather holes from whence they came !
The carbs are nice and clean so I will have a look. .....silly question. ...where exactly am I looking ?

 

Something flapping about loose with just one nut and a hole in a bit above it should be fitted too. Near top of the carb just behind the choke.

 

All lock nuts present and correct. Tried leaving with ignition on a few seconds longer than normal to see if there was any change. ..there wasn't.
Lock nuts are on a threaded bar and gentle pressure increased revs. ..is there possibly adjustment to do there to increase revs, or will that just make engine rev more all the time ?

 

It should set when you press the pedal before starting. Perhaps you've been accidentally setting it and now changed your start-up routine?

 

Just depress the pedal once then start engine. I must admit that since having electric pump fitted, the noise does make me do the procedure more quickly !

 

The pedal pressing is mechanical, you can do it before you turn on the ignition and start the pump.

 

What noise, when?
