14. The accelerator pump discharge nozzle may be removed by loosening the Phillips head screw
and inverting the main body over your hand (Fig. 9). When this is done, the nozzle, screw, and the
discharge check needle should fall out. Care should be used in reinstalling the Phillips head screw
so as to not strip out the threads.

15. The final major disassembly step is to invert the carb and remove the six Phillips head screws that
attach the throttle body to the main body. Once the two pieces are separated, the main body
gasket may be removed. Before discarding the old gasket, match it up with the new one to insure
that the proper gasket finds its way onto the main body during reassembly.
16. Use carburetor cleaner, available at most automotive parts stores, for cleaning.
17. When reinstalling the metering plate on the secondary side of Model 4160
™ carbs, the contoured
gasket is placed on the plate first. Then, the thin metal shim plate is placed on top of the
contoured gasket. Finally these three pieces are placed on the large rectangular gasket (Fig. 10),
and the four piece sandwich is then placed on the main body, and the six main body clutch-head
screws are tightened. Gold, Silver, Sports Claw
, and Demon™ carburetors, along with HOLLEY®
model 4150 ™ carbs, which are fitted with a secondary metering block, are assembled in the same
fashion as the primary metering block.
