SU Carburetors like new

This time I had all I need...

 
 
The new parts I needed were mostly :
- the rubber holding the tank in place as I noticed they hold the tank at the right position and when it's in the wrong position the choke moving mecanism jams
- the butterfly shaft as they were really badly worn and surely creating a leak. The wear is impressive


Was exciting to put it all back together, I was worried I might forget what goes where and I did have to dismantle several times after I put back together as I did some steps in the wrong order.

I cleaned them best I could and they look really nice now. Notice on the left the bag of parts that have been replaced, even the needle is new.


Moment of excitement as I install these back on the car. Refilled the inside of the pots with 20/50 engine oil. Did some basic tuning, not sure how good that is but that will have to do for now. Looks so good and the engine runs weh eh !

I used the following technique to tune, from an article I found on classic car magazine uk. Thanks to them, that got me started and I found it simple to understand.

  1. By the way, I had to add 2 additional springs to pull back fully the throttle in place, hopefully that's just temporary while the shafts settle in place as start wearing a little bit and move back more easily.
