DESCRIPTION
1. DESIGN
Holley Carburetor Model 2110 Series
are all
dual downdraft carburetors. These dual
carbu
retors can be considered as two carburetors
built
side by side into one unit, but utilizing
the same
carburetor air inlet. Each side has
its own idle
system, main metering system, and
throttle plate.
All air bleeds and vents are supplied
with
filtered air from the air cleaner,
giving added
protection against the accumulation
of foreign
matter in the carburetor passages.
The main jets and idle tubes are individually
flow tested to insure precise calibration,
and meter
all fuel used during part throttle
conditions. The
accelerating pump system provides
the added fuel
for acceleration. An "override"
spring feature of
the accelerating pump, prolongs the
discharge of
fuel for smoother acceleration. The
added supply
of fuel necessary for high speed or
full power
operation is delivered by a fully
automatic power
enrichment system actuated by pressure
differ
ential acting across the economizer
diaphragm.
The booster venturi nozzle bars minimize
percolation effects by providing a
larger main
well with a long vertical rise. Percolation
occurs
on hot days after the engine has been
shut down.
The fuel in the bottom of the main
well is heated,
forming vapor bubbles which trap raw
fuel between
them as they rise. This action drains
the fuel
from the carburetor and deposits raw
fuel in the
intake manifold, making it difficult
to start the
engine. By incorporating larger main
wells and
longer passages, the bubbles break
as they rise.
No liquid fuel, therefore, is carried
into the hori
zontal passage leading to the main
discharge
nozzle.
