Carby Back On

Decision made... carby has gone back on so we can check the timing and give it a tune.

Managed to remove the old carby to inlet manifold gasket intact (enough!) to use it as a template to make up a new one. A quick clean of the manifold and carby mating surfaces to remove any rubbish. Kept a rag in the inlet manifold to stop grit entering the engine and made doubly sure by giving it a vac. Blew out the carby with compressed air to remove any grit in it.

All went back together no probs.

I've ordered a rebuild kit for the 4GC, so when that arrives hopefully we will have tuned the engine ready for the carby to come back of for a rebuild.

In other news, it looks like I have found a 2nd hand choke (c/w internal mechanism) in the States... stay tuned.

Choke

So the choke mechanism is frozen solid on the carby; time to investigate.

First, a boring reference shot to show the original position of the choke mechanism...

Now down to business.

Cover screws came out, but she no budge. A couple of very light taps with the "gentle persuader" and voila!

Ooookay... so *that* is why the choke was frozen solid! The spring backing plate just crumbled away such was the rust.

Time to source a replacement choke mechanism.

Carby is off + other stuff

So the Rochester 4G-C came off today in readiness for being pulled down...

Also... the reverse lights fuse (10A) is blown, so hopefully that is an easy fix.

AT Cooler Hose

The Impala went back up onto stands, ready to cop a new automatic transmission (AT) cooler hose.

You might remember the first fix done on the Impala was tightening a clamp on one of the AT cooler hoses. Closer inspection showed that hose was a mish-mash of solid line clamped to rubber hose in various places... so now it was time to finally tidy it up!

Before...
