We've had BOB for nearly seven years now and the choke cable has always been 'a bit dicky.' Nothing terrible, it worked, but felt odd.
Last month the choke cable on my motorbike seized up - dirt had got to the plunger and blocked it such that the outer cable would push out of its housing at the lever and the choke failed to operate. Solution for that bike (KLR 650) is to replace the cable with a plunger on the carb which you can access easily.
Last week BOB's cable started to the same thing, except I could operate the choke but not turn it off. It turned out the outer cable had detached from the back of the plunger housing! Bugger.
As i'm sure you know, it's not practical to get out of the car and manually operate the bloody thing, and it's winter here in Queensland (under 20 celcius somedays!)
But then I found a garage 5 miles away who makes up any cable you like to order. We dropped in the inner on the old plunger and outer with the original plunger housing, and two days later picked up a new inner and new outer bonded to the plunger housing.
And all for $30.
... now where the bloody hell did I put the ferrule!
