7/11/2004: Carb Rebuild
Although my car is a 1966, it has an engine from an earlier 118H
car. I am going to keep this engine in the car, even though it’s not
technically correct.
One of the differences is that it has this older, simpler carburetor,
the Weber 28/36 DCD. Rebuilding it was a very satisfying project.
I mostly followed the process outlined in the Haynes
Weber Carburetors book. The FIAT 118H Service Manual was also very
helpful, since it had nice photos of the fiat-specific linkage, and
contained tables with the specific jetting and float settings for this
car.
First, the pictures:

| Before |
|
| After |
So cool. Here’s a photo essay of the rebuilding process:
|
| Took off the carburetor cover |
|
|
| Look at the crud in the float bowl! |
|
|
| Removed the float pin.. |
|
|
| Removed the choke device cover. Note that the linkage was painted black. I’ll reproduce that. |
|
|
| Parts were cleaned in a chemical dip. |
|
|
| Before and after- it really cleans things up nicely. |
|
|
| After completely stripping it down, the body was cleaned in the dip. |
|
|
| Much cleaner now. |
|
|
| Linkage parts from the primary throttle shaft, before. |
|
|
| And after. Painted the linkage parts black, as they were before. Cleaned everything else, and gave the spring a little silver just to neaten it up. |
|
|
| Put the throttle plates back in, with loctite green. |
|
|
| Put all the jets back in, reassembled it, and done! |
