Fine Tuning Your Carburetor
Although I have tuned countless carburetors over the years by “ear”, I decided I wanted to make sure I had tuned my trucks new carburetor to be as efficient as possible. Especially since my hearing is NOTHING like it used to be!
Tuning Carburetor With Vacuum Gauge
The next step in carburetor tuning is via a halfway decent vacuum gauge. You connect the gauge to a vacuum source – in this case I connected to the line right off the intake manifold that runs to the vacuum advance unit on the distributor. I immediately saw a wobbly reading of approximately 16.5 inches of vacuum. After adjusting the mixture, it rose to a little over 18 (you want to see between 18-20 or so) and was pretty steady. Also, the periodic “puff” in the exhaust decreased, which was good.
Read MoreL and R-Series Library
For those of you that used to frequent the previous website – “Restoring Cornelia”, I have great news. I just completed transferring the L and R-Series documents from the site and have created a new “R-Series Library” page for you (contains as much L-Series information as R-Series, though).
In the new library you will find the MT-97 Parts Catalog, an Inter-Sub Manual from 1959, the CTS-11 Service Manual for L-Series Trucks with the CTS-12 R-Series supplements, a Carter YF Service Procedure for rebuilding the carburetor, the CT-62 L-Line Product Information No. 2 Sales Guide, and a Wiring Diagram for R-Series Trucks.
