hello, i need some help, i dont no why by this is how my (carb) i think is operated? How do i get this back to standard? Could it be why it idles quite high?
Christ thats a hell of a spring You should have a little one that goes on the throttle arm its self dude
That is some return spring! It must be putting a great deal of strain on the butterfly spindle...a little surprised that the arm doesn't appear to be bent. Thinking about it, it is possible that the throttle stop screw has been wound in to open the butterfly a bit to stop it jamming in the carb throat...with that spring and the leverage it could stick. The spring normally goes between that lower fixing (as used by the current monster ) and a lug coming off the carb body about 6cm above it. Replacement spring...try the usual suspects..Cool air, JK, or VW Heritage. Must need weighted boots to operate the throttle as it is.
It looks like the arm that the spring would normally attach too to broken/removed. It should work fine as it is but the spring is quite hefty for that application. Does the spring allow the arm to return the lowest step on the cam?
Sorry but the geometry of it is all wrong...at one point that spring is trying to open the throttle. Assuming that its pure chance that the throttle stop screw is only resting on the third step of the fast idle cam instead of the fourth then if it really was on the fourth step the lever would be floppy as the spring may be doing nothing, judging by the angle of the spring pull in relation to the lever. Of course one way to remove that slop would be to screw in the throttle stop in until it met the cam which would then result in a high idling speed.
