Grubby looking original VW Solex carb. I'm slightly worried that this might be yet another thing that I take apart and leave in a tin for 4 years. |
 |
Undo the 2 nuts holding it to the engine, unplug the 2 electrical connections, detach the throttle cable and it lifts free, quite straighforward really. |
 |
A view of where the carb was mounted....oh god what have I done?!
You can see the throttle cable coming through the tinware into the foreground. |
 |
Carb out side view. |
 |
The other side. |
 |
Undo the 5 screws on the top and the top and bottom come apart...man I hope this ends well. |
 |
The gasket is broken, which may explain the fuel leak I saw a couple of days ago when trying to start her. |
 |
Gently lifting out the small plastic clip and the tank lifts out. |
 |
Removing the fuel inlet needle valve, the rebuild kit contains a replacement...although this one looks in pretty good condition. |
 |
Removing the brass emulsion jet (step 08 in the guide). |
 |
Just about to remove the choke mechanism, as suggested by the guide, I have scored the casing so I can align it correctly when I reassemble. |
 |
Choke mechanism removed, there's a grain of crap in there, probably not causing a problem, but its convinvced me that I'm doing the right thing by stripping and rebuilding it. Its probably the original 1976 carb ... so that's pretty old ;-) |
 |
Unscrewing the fuel cut-off solenoid (after using a spanner to loosen it of course), I intend to test it with my bench PSU (step 06 in the guide). |
 |
Unscrew the idle jet (step 11 in the guide). |
 |
Having removed the 13mm blanking plug, I'm unscrewing the main jet (step 09 in the guide).
The inside of the tank looks like the inside of a coffee percolator I used to own. |
 |
Removing the idle mixture screw (step 10 in the guide). |
 |
Removing the idle speed screw (step 10 in the guide). I forgot to take the advice about notiing how many turns out these were from being fully screwed-down, which means setting this back up is going to be more tricky than it needed to be....doh! |
 |
Accessing the accelerator pump... |
 |
...accelerator pump... |
 |
I used a stanley knife to gently prise away the accelerator pump diaphragm (step 12 in the guide). |
 |
I followed the guide above and mostly it was really straightforward, the only thing it didn't really explain was how to remove this brass jet. I spent 5 minutes looking for some tiny screw or flange but actually you just carefully twist it from side-to-side and it comes loose. |
 |
Brass bits in a bowl ready to be covered in Cola and left overnight, the phosphoric acid should clean them up nicely without damaging them. |

You basically work back through the steps in reverse until voila, a nice clean rebuilt Solex.. |
