Default Re: Columbia Carb linkage, please help!

You may want to post the year of your cart. Generally, the carbs all go on the same way but I don't know the "newer" Par Cars very well and I want to make sure I am not giving you bad advice.

It is really tough to describe how those carbs attach. Of note is that a confusing part of these carbs is that they are backwards from most. With most carbs, the throttle is closed when nothing is acting on it. In other words, if you get a new one out of a box the throttle is closed in it's resting position. With the Walbro carbs used on most Par Cars this is exactly opposite. If you get a new one out of the box the throttle is sprung so that the carb is at full throttle at rest. The cart's throttle linkage pulls the throttle closed when the accelerator pedal is pressed. When the gas pedal is pressed the linkage pushes the carb's throttle open. I know it's confusing but if you can get yourself to understand how these carbs are unique to most others it could be helpful.

It sounds like you can use a repair manual so see if you can find one here:

Here is how to connect things the factory correct way:

1. It looks like you have your carb on the cart right. I have found that it's easier to attach the linkages (throttle and choke) prior to attaching the carb to the cart.

2. The choke linkage is simple. You shouldn't need much help with that.

3. The carb's throttle lever should have two holes and your linkage should be curved 180 degrees with a very slight 90 degree bend at the very end. It's not unusual for that last 90 degree bend to break. If so bend a new one on.

4. The linkage needs threaded in one hole, reversed, and threaded through the other hole in the opposite direction as the first.

5. That little 90 degree bend should hook onto the throttle lever and enable the level to be pushed closed when the gas pedal isn't pushed.


Here another way of connecting things:

1. Go to an auto parts store and get a cable of cable stops (see pic)

2. Straighten the hooks on your linkage.

3. Put your linkage into just one throttle lever hole, with a cable stop on each side.

4. Pull the throttle lever closed and tighten the stops with them being flush against each side of the lever.


Sorry about the long response. Good luck!
