Carburetor - New Float Level Gauge

84olds4

SUBJECT NEW FLOAT LEVEL GAUGE FOR DUALJET AND NUMBER: 84-T-17
QUADRAJET CARBURETORS

DATE: Sept. 5, 1984

MODELS/YEARS ALL MODELS
SECTION: 6C

FIGURE 1:

Enclosed are three new External Float Level Gauges that have recently been released for checking the float level in all current Dualjet and Quadrajet carburetors. See Figure 1..

The new gauge, part no. J-34935-1 or BT-8420A, reflects the design variables of the past several years that have led to occasional inconsistent readings when the older gauge was used. The new gauge is also suitable for checking the float level of all past model Dualjet and Quadrajet models, and in checking Mixture Control Solenoid plunger travel.

FIGURE 2:

The procedure for external checking of the float level has not changed. See Figure 2.

FIGURE 3:

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 gauge replaces J-9789-130 or BT-7720, which should be discarded and SHOULD NO LONGER BE USED.
