engine and drivetrain Carb Linkage - Spring???

[paulram]

Running a 32/36 Weber.  Having issues with the carb getting to wide open.  I adjusted the pin at the linkage. I then adjusted the pedal as per previous post by mlytle.

 

I realized there is a rusted out spring at the pedal. 

 

Question is... Is the spring at the linkage (shown in picture) a cheap fix because they did not fix the pedal spring?  If I replace spring at pedal, do I need spring at linkage.

 

Right now I've realized there is not enough leverage to get throttle wide open as the spring is too heavy.  Can I remove spring or is it necessary and I need a lighter one.

 

Thanks again.  Every time I think it is one thing, it goes one thing deeper.

That looks like the correct spring, you do need it.  If it has been replaced with one that is too stiff then you could find a lighter spring, it just needs to return the carb to idle when you let off the gas.  If you replace it make sure there are no obstructions to the new spring that might cause it to hang up.

From what I can see of the picture, the spring isn't connected per the factory.  IIRC the spring extends down from the linkage and is longer than that short one in the picture; the upper end is attached to the bell crank arm, and the lower end is attached to the firewall.  Some care must be taken when positioning the spring, as it can be installed in such a way that it rubs against the heater hose.  That will not only wear the hose, but will impede the throttle returning to idle when you let off the gas. 

 

Look in the shop manual or at another 02 to verify that your spring is the correct one and is properly installed.

elaborate on the rusted out pedal spring........

 

that little spring in your picture should not be stiff enough to prevent you from puttting your foot down unless it is too short and runs out of spring.  the right foot should be able to over power anything you can put in the linkage system.

If memory serves I was able to find a spring that was close at PepBoys.  Measure the distance between the hole in the bracket up at the top of the firewall and the hole in the linkage - then get a spring that is slightly shorter than that distance.  Should take a slight effort to depress the linkage by hand, but should return rapidly to its "at rest" position.

 

And, as mentioned above, make sure the lower hook that connects to the throtle linkage is installed with the hook facing toward the front of the car.  Otherwise it can wear on the heater core return hose.

When I went to adjust the pedal, I removed the nut and a loose spring was on the same shaft the pedal adjustment was on. It iooks like it is meant to snap the pedal adjustment back to its position. It is rusted and bRoken.

you need to put a good one in there.
