[xj] Color Tune and Churchhill Tool

LIst:

I spend the afternoon tuning the carburetors with a Color Tune, Air Flow Meter and Churchill Needle Adjustment tool. I bought the color-tune and needle adjustment tool last winter and wanted to use them before I get into the damaged valves.

The color-tune, which allows you to see the color of the ignition inside the cylinder (Yellow too much fuel, blue correct amount) is a good guide although not the be all and end all. The air flow meter, measures the amount of air moving the carbs allowing you to synchronize the flow between the two (or three of you have them) carbs. The needle adjustment tool allow you to raise and lower the needle, which in turn enriches and leans the mixture.

Now you know why there’s fuel injection and computers.

Next week I will remove the valve covers and measure the lash as we begin the errant valve odyssey, similar to a Greek tragedy, except British.

Someone lash me to the mast as we drive by the used British car dealer, so I can’t hear their exhaust song.

A warning that you are starting down that ‘‘slippery sloap’’. Soon
the value of your special tools will exceed that of your car. Doom
awaits. Have fun. Pete–

A second car is essential so that you can compare measurements by your
special tools on the well-running car. Whichever that happens to be on a
given day.

Not to mention that an additional vehicle brings down the cost per vehicle for the special tools Economy of scale, a sound business principal.

Warwick:

There’s a picture here: http://www.buckeyetriumphs.org/technical/Carbs/CarbsIII/CarbsIII.htm

It consists of an Allen wrench, about 12" long and bent in an “L”.

The Alllen wrench is slides into a close fitting tube about 6" long. Due to the L shape, the wrench cannot slide through.

The tube fits into the air valve of a Zenith Stromberg carburetor, the Allen wrench adjusts the needle up and down to increase or decrease the flow of fuel through the carburetor bridge. Its purpose is the fine adjustment of mixture, lean to rich. The tube grasps the air valve and prevents it from turning when torque is applied to the needle which is threaded into the air valve,using the Allen wrench.
