I finished removing the SU carburetors from the car. It was difficult to get to some of the nuts that hold the carbs to the intake manifold, particularly the lower ones, and this job took me about ninety minutes to complete.
This is how the carbs looked before I started. The first thing I did was to remove the choke cables that connect to each of the two carbs, one on each side.
There are fuel hoses that connect across the tops of the carbs as well as two hoses at the bottom. I disconnected all of these next.
There is also a smaller hose that connects to the front carb only and then runs over and terminates by the distributor. This hose is for the distributor's vacuum advance.
There are four nuts that hold each carb to studs on the intake manifold. I used a 13mm box-end wrench to loosen the top nuts first. There is a heater hose that feeds the heater core inside the car--I found that by removing this hose connection I gained some area to maneuver towards the two lower nuts.
A 13mm wratcheting wrench was also helpful in getting these loose on the front carb first. Then I removed the front carb entirely in order to gain better access to the lower nuts on the rear carb.
It was tricky to reach those lower nuts on the rear carb, but I was able to get them off by standing in front of the car and using a box-wrench and wratcheting wrench once the nuts were loose. Once those nut were off the rear carb came right off the manifold.
Here's a shot of the engine bay following my most recent work.
I ordered the "Just SUs" video from
zTherapy last week and hopefully it will arrive during the upcoming week. Once I've had an opportunity to review the video I'm hoping to be in a position to dig into the carbs and see what, if anything, needs to be replaced or rebuilt. In any case I will be giving them a thorough cleaning.
