carb missing parts?

Post by Swagon »

i was doing a tune up on my swagon today and noticed that only one side of my carb is actually working, the right side door isnt opening or jetting fuel. now ive been driving it for a while and i think its been like this the entire time ive had it. its dangeriously slow to get on the freeway and i think this could be a good reason why. it looks like im missing a spring that attaches the second linkage in the back to the left linkage. i also notice that i think some things are bent. anyways i would be highly interested in a picture of the back side of someones carb so i can see what mine compares to everyone else.

ohh i also was wondering if everyones 4wd disengagement sucks to get out of.

I think you are referring to the secondary throttle plate? the primary throttle is on the left side as you look at it from the front of engine bay, and the sencondary is on the right. The secondary operated by a vacuum diafram that is located in the chamber beside the throttle bell crank (where the cable attaches). often this diphram gets worn out and will leak, so the secondary does not open. however I do not think it is easy to open the secondary by just advanceing the throttle, but there is a test for it in the factory service manual (link at the top of the page).

If getting your car out of 4wd is difficlut it is usually from having tires that are not the same size, or worn unevely. first fill all your tires to about 38 or 40 psi, that usually solves it, check they are all the same size at least, and preferably the same brand, and worn evenly. It is easiest to get it out of 4wd by allow the car to roll backwards about 4 or 5 feet (it unloads the drive train), and it will slip out. Even with all the same size tires inflated properly, it will not be easy to get it out of 4wd unless the steering wheel is pointed straight and the car rolls freely. Poor front wheel alignment for example could make it difficult to get it out of 4wd. It is a matter of strain in the drivetrain, different size tires, misalignment or not having the car rolling strait ahead will all put strain on the 4wd.
