General information
The IKOV carburetors built in the Urals motorcycles, type 2928 CE,
make the enterprise possible of the engines with the basic
adjustments in accordance with the data listed in the manual:
General data:
- even no-load operation rotational speeds of
the engine from 650 to 800 RPM
- harmful waste gas emissions not over CO=42 by km
- reference value fuel consumption by 100 km: 7.8 l
- engine temperature in the cold weather starting: over -15° |

Carburetor attitude
1. The fuel level in the schwimmergehaeuse should, based on the dividing
line between
Carburetor body and schwimmergehaeuse, with an atmospheric pressure of
1.837 Mpa,
11 + /-1 mm amount to.
2. Each carburetor must be
adjusted individually in the no-load operation.
Adjust as:
The screw
of the gas course so far screw in that between screw and cable one
Column of 2 to 3 mm develops
Remove a spark plug and
ground the inlet.
Adjust the throttle adjusting screw in such a way that the engine runs
regularly with minimum speed.
Turn the air mixture
adjusting screw to the terminator point and locate the position, in which
the engine works regularly.
Place with the throttle
adjusting screw the minimum rotational speed, in that
the engine in the no-load operation regularly works.
3. The air fuel mixture
knows loads or climate for special conditions punkto by means of
Throttle aristocracy to be adjusted.
4. The synchronous enterprise
of the left and right cylinder with different modes of operation becomes
with simultaneous lifting throttles of the right and the left cylinder
reaches. If you
not sufficient experience has to stop the synchronous running with the
hearing can a speedometer be used. For this purpose on the measuring
conditions place the motorcycle, that
Engine start and into the fourth course switch. With 50 kmh and during
that the engine on two
Cylinders accumulates, the spark plugs one after the other one
interrupts and the carburetors
synchronous run stop. Permissible is not an asynchronous value of any
more than plus/minus 5 kmh.
Carburetor maintenance
Control regularly the attachment of the
carburetor and its individual parts. If fuel from the discharge
openings steps, that means that the fuel valve is leaky. In order to
repair this, the fuel supply system must be washed and examined and
fastened or repaired the fuel valve.
All 5000 km must the parts fuel - and
air supply system be washed and with air pressure blown through.
