Double versus single throttle return spring

[bobfather]

Having covered 40k miles with a double throttle return spring I started having trouble throttling up from a cold start and my friendly mechanic commented that the throttle pedal was unusually stiff for a Chimaera.

I am aware that the cable end pip can separate under tension and that the cable / sheath interface can become sticky. I decided to re-oil the cable following a method I found on PH. Before doing so I removed one of the throttle return springs and tested how the car responded. Hay-presto the problems have all disappeared. Removing the excess tension has removed the sheath stiction issue and cold start is OK now because control of throttle fine adjustment is now possible. No oil needed.

My question is, are there any down-sides to running on one spring.

Seen to remember this coming up before, someone suggested it was worth keeping 2 springs in case one failed, then the throttle would not be left open. Not sure of the chances of that happening though!

There is a 3rd spring if you look closely,
But two main ones, I lubed the cable and removed one spring and was happy with the results

I keep the second spring in the car just in case

IF! It stays open just turn the ignition off and push the clutch down

Has been discussed a few times before.

I have gone for the two lighter springs options and cable regrease. Works well for me.

+1 I only run one. much lighter and I had the throttle stick open when it got caught under the mats, i just dipped the clutch as above.

Thanks folks, second spring is in my essential spares kit in the boot. I'll keep it like it is, throttle response seams so much better with the lighter pedal

Can anyone link me, or give me a rough How-To for greasing / oiling up the throttle cable as mentioned above?

Cheers,

Slightly O/T.

I tried to turn a eurobox engine off that was on the side of the road revving it's nuts off when the cable snapped, it's woman owner shrieking in panic mode.

It was so hot and revving so high, it was still running with the ignition off, presumably dieseling!

I had to jam it in gear, dump clutch and sit on the brakes, still took about 10 seconds to die with the clutch slipping

Malc,

This thread give some good tips, particularly the blue tac / funnel idea, wish I had read that before I spent hours dripping oil into the cable.

Best thing to do is remove the springs of choice then pull each one far back as possible then let go on to your leg !The one which hurts the most I would use
