 Re: Sticking throttle I think heat expansion in the spring is the cause. It's right above a very hot part of the car.

It's right above a very hot part of the car. but the carb always runs cold due to the way it works - that's why Citroen added a heater to it  the plastic cables (when worn?) tend to get "grippy" when hot you can feel it in the pedal in those long bank holiday standstills.

Re: Sticking throttle Thanks for all the top tips  It's the Mehari and it does seem to get worse when the car's hotter.... I'll have a fiddle next week when I'm back with her. Sam

Re: Sticking throttle I'm running an experiment. I've put a 22mm copper pipe as a sleeve over the spring. I'll let you know if it makes a difference by the end of the summer. Summer?
