Throttle spring
Turbo Mini Forums

I got my mini as an unfinished turbo project, and I've noticed that the throttle doesn't close all the way. It looks like the spring isn't strong enough to pull the pedal back up. Should there be a spring external to the carb, or does it just rely on the clockspring type thing on the throttle shaft itself?

There should be a spring either end of the carb body on the shaft.

When it closes itself, can you manually close it yourself, or does the butterfly just not look flat?

I just need to touch the end of the throttle cable and it flicks back to the fully closed position.

Is the cable and the carb all connected up to the car, and you mean the accelerator pedal? Not sure what you mean by touch the end of the throttle cable!

Yes, it's all in the car. I seem to have sorted it now. One of the springs wasn't doing much because it wasn't located properly.

I have the same problem but backwards.

When I press the pedal to the floor, the throttle is not wide open as in 90° to the bore.

I retrofitted an HIF 92 Mini with an HS4 (car was originaly 1275 but due to budget constraint is now a 998) but according to Minispares ther is only one accelerator pedal.

Any ideas ?
