This will introduce a fair amount of 'bypass' air into the mixing chamber when the ambient temperature is fairly warm (90F plus) - probably having to do with decreased air density as well. Turn on the burner real low and observe what temperature the TC's start to open.īased on much experimentation, I found that the plunger should not start to open until around 115F at 125F it should be about half open, and at 140F the plunger should be fully open. Place a cooking thermometer in the water. Fill a pan with water, put it on the stove, and place the TC's in the pan so they are completely covered in water and position them so you can observe the opening and closing of the plunger(s) together.

This will take some trial and error, but will be worth the trouble.
You now need to 'balance' (if you have multiple carbs) and adjust the opening rate of the plastic plunger. At room temperature they should be straight, however you may find yours bent because the DPO screwed down the nylock adjusting nut too much and bent them.Īfter straightening, put them back together and gently tighten the adjusting nut until the plastic plunger just seals the opening in the cylindrical extension of the TC housing, then tighten it one more turn. I imagine the procedure to be identical for any ZS carburettor fitted with TC's.įirst remove the bi-metallic strips. The following is the procedure I used on my 1974 1/2 model TR-6, fitted with Zenith-Stromberg 175CD-SEVX carburettors.

The specifications on how to adjust the TC's were a closely guarded secret at the Zenith Carburettor factory and were never revealed to any known, living person! However in doing so, you must remove the adjusting nut, and unless you knew that the middle nut was an adjustment.you were doomed. When this happens the owner usually pulls the TC's apart, removes the bi-metallic strip, cleans off the gunk and puts it back together again. The other end of the strip engages a plastic plunger with a conical end which slides in a cylindrical extension of the housing and thus forms a regulating valve.Ĭhanges in temperature causes the bi-metallic strip to flex, moving the plunger in its bore, regulating the annular area around the bore thus controlling the amount of by-pass air that is allowed into the carburettors mixing chamber.'Ī common problem with the TC's is that the plastic cylindrical plunger becomes stuck, either open or closed due to buildup of gunk. 'The temperature compensator (TC) is a rectangular housing with a plastic cover that contains a bi-metallic strip, one end is secured to the housing with a screw or rivet, and an adjusting nut is located part-way along its length. To paraphrase the Haynes 'Zenith-Stromberg CD Carburettor' owners workshop manual:

Understanding the Zenith Stromberg 175 CD2 carburetor 19 February 2009, 03:59 I thought it might be useful to gather together advice on understanding the various features, mainly lesser known ones in the first place, of the Zenith 175 CD2 carburetors and their adjustment and possibly post them to the Wiki page on the Forum.
