I currently have a Carter WA-1 carb on my Champion 170. The research I have done tells me this carb was used on cars about 10 years before my '52 truck was made. The records suggest there should be a Carter BBR1 carb on the truck. My first question, is there a big difference in the Carter carbs of this era? I have seen WA-1, WE, BBR1, AFB, W1 etc. How does the WA-1 compare to the BBR1?
It looks like my carb was added at some point in the past and someone did some jerry rigging. In the first picture you can see the cover of the "Carter Climatic Control" is missing (not sure what this is suppose to do) and I have not seen a choke cable attached to the side as mine is. In the second picture you can see there is not only a hole in the valve but it does not close completely when the choke cable is pulled (choke cable is fully pulled out in the picture). This may explain my difficulty in starting it when cold. The valve is completely vertical when the choke cable is pushed in so that is correct. The bowl above the valve (red H in picture) has also been taller in other pics of WA-1 carbs I have seen.
Are the various carbs interchangable? That is, could I remove the WA-1 and replace it with a BBR1 without too much difficulty? Is it worth changing? I assume the mounting holes would be the same.
Anything else you see wrong? Third picture is just another view. For the limited driving I have done since getting the truck, it seems to run well. I am not familiar with Carter carbs but I assume they function pretty much the same as other brands.
