Carburetor - New Float Level Gage
Number 84-6 (Gasoline)-39 Date 8/84Subject: NEW FLOAT LEVEL GAGE FOR DUALJET AND QUADRAJET CARBURETORS
FIGURE 1 - QUADRAJET/DUALJET FLOAT LEVEL GAGES:
Enclosed are three new External Float Level Gages, as shown in Figure 1, for checking the float level in, all current Quadrajet and Dualjet carburetors.
The new gage, Part Number J-34935-1, or BT-8420A, reflects the design variables of the past several years that may have led to occasional inconsistent readings when the older gage was used. The new gage is also suitable for checking the float level of all past model Quadrajet and Duaijet models, and in checking Mixture Control Solenoid Plunger travel.
FIGURE 2 - FLOAT GAGE - EXTERNAL CHECKING PROCEDURE:
The procedure for external checking of Float Level has not changed. See Figure 2.
FIGURE 3 - CHECKING SOLENOID PLUNGER TRAVEL:
The procedure for checking Mixture Control Solenoid Plunger travel on E4MC, E4ME, E2MC and E2ME models has not changed, and is outlined in Figure 3..
The new gage replaces J-9789-130 or TB-7720, which should be discarded and should no longer be used.
