Additional throttle return spring recommendation?

Recommended Posts

Can anyone recommend a suitable spring to use as an additional throttle return spring? My idle is still creeping up when the car is hot and I want to see if I can assist the throttle in closing more effectively.

Hi Ian,

 

I would be surprised if no one on the forum, with a CP car has not come across this problem,

 

If no one can help,Malcolm Jones @ Prestige Injection,or Neil Ferguson on this forum will give good advice.

 

Regards,

 

Malcolm.

I have three,one on each throttle lever, to clips on adjacent cylinder head studs.

 

But the problem is more likely to be that the butterflies we'd adjusting on the spindles. I had to adjust mine minutely until they gripped a 1.5 thou feeler top and bottom, before the fast idle went away.

Be carefull not to apply too much extra load on the spindles, this will accelerate wear.
