Sorting It Out

Back to it. This is the cam sprocket that was in there, the pin is all chowdered up, lord knows what they were doing when they were installing this.

Again having a parts car really saves the day, here's a clean pin.

That sprocket was worn.

Clean up the front of the engine best I could. The new timing set is coming, so off to work on some other part.

The thermostat was in there and it was closed when I removed it. However when manually trying to open it, it's really grabby and sticky. So it makes sense it was sticking as the engine took forever to barely warm up.

Here's the carb that will be going on the car. It's a 4100 with the 1.12 venturi for a decent sized engine. The 1.08 is usually for small blocks. For those who think the Autolite 4100 is a performance carb you may wish to read this with a grain of salt. Autolite 4100. Even though it doesn't flow high numbers it does seem pretty darn good at metering fuel with its annual boosters and it pretty responsive for a stock FE.

There's where the size it located.

We had rebuilt the carburetor several years ago and a few years ago it was used for this fine apparatus. However whilst this '68 LTD has a Z code 390, it's been chugging on 7 cylinders for the last 2 years and the secondaries weren't opening due to lack of vacuum. As a result the secondaries became seized.

But some penetrating oil and a little heat to lower body and it freed right up. I removed the blades and shaft and polished the base bores and shaft.

The body after being disassembled received a thorough cleaning and the small jets like the enrichment system were cleaned with wire.
