Hi the paragraphs under this have been harvested from previous answers on this site , mine choke stuck solid today after weeks of no bother ,I fiddled with the chokes (on my own ) so I don't know what "cured" it ??????
Any hints very welcome
My choke frequently gets stuck so I can't pull the knob. I think it's sticking at the knob end, and the choke warning light never comes on so I wonder if the switch is jamming it somehow.
Just to expand on Dave's advice: if you look at where the cable attaches to the LH carb, you'll see it operates a cam to raise the tickover speed when the choke is on. This is why it is advisable to press the accelerator pedal slightly as it reduces the strain on this cable. It is also a good idea to check that this cam is greased.
The OE cable is designed so that the knob is pulled out to the desired setting then turned slightly clockwise to hold it there. To release the choke requires a slight anticlockwise turn and a push.
If you have the standard set up, it is good practice to put your foot on the accelerator before pulling out the choke. It makes it much easier and puts less strain on the cable
I'll have a suspicious look at the fast-idle cam with a helper trying to pull the choke knob. Maybe it's that bit that's not working properly, because after a few minutes of wiggling the knob it's very free moving when it actually moves. I'm thinking that maybe the angle that it pulls on the cam might not be quite right to get it starting to move.
