Note:Do not open the throttle while kicking the engine over since it
may flood the spark plugs.
To start an engine that is flooded, first open the throttle fully, hold
it there and give the engine up to 10 swift kicks It should start. If it
still doesn't fire, take the spark plugs out to see if they are wet with
gasoline. If they are wet, dry them. Clear excess gasoline from the
cylinders by kicking the engine over 10 times with the plugs out
and the throttle closed. Then replace the plugs and repeat the
starting procedure described at the beginning of this section (1).
For
electric starter
models: Set carburetor enricheners and/or air
restrictor as with kick starting. Unlike manual starting, however,
the gearbox does not have to be in neutral as the electric starter
may be engaged with the clutch lever pulled in, or with the
gearbox in neutral. Make sure the kill switch is set to "run" and
push the starter button to turn over the engine. Immediately take
the carburetor enricheners off when engine starts. After 2-3
minutes of running, open the air restrictor also.
2. When the engine has been standing for several hours but the
ambient temperature is high (60°F/15°C degrees or above), try
starting it without any choking. If it doesn't fire, use the procedure
described below.
3. When the engine is cool or cold and the ambient temperature is
between 40°F-60°F/5°C-15°C, depress both enricheners to start.
As soon as the engine starts, immediately retract the enricheners.
Run the engine at moderate speed for 30-60 seconds. If it starts to
die, tickle the twist grip throttle (rapidly twist part way towards full
throttle and then back off) to keep the engine running. Close the
choke about ½ of its travel if needed. As soon as the engine runs
smoothly without sputtering at the ½ backed-off choke position,
fully open the choke and keep the engine running. If the engine
sputters, put the choke back to about ½ of its travel for about 30
seconds. After 1 to 3 minutes, depending on ambient temperature,
the engine should run smoothly with the choke fully open.
4. If the engine is cold and ambient temperature is below 40°F,
first, give the engine 5-10 (depending on how cold it is) priming
kicks with the ignition off. This will get some oil circulated to key
internal parts. Depress the enricheners on both carburetors and
also leave the choke fully closed. The engine should then fire
within 5-10 kicks, depending on how cold it is. For example, when
the ambient temperature is 0°F, it typically takes about 5-10 kicks
to start the engine. As soon as the engine starts, back the choke
off 1/3 of its travel and raise (retract) both enricheners (labeled
"choke" in Mikuni carburetor). Then follow the running procedure
described in item 3.
Note: It is very important to back off on the enricheners and choke
as soon as the engine will sustain itself without sputtering. Since
the URAL is an old fashioned engine design, the plugs will foul
quickly (as soon as one minute) if the engine is run too rich. If one
plug fouls and the other doesn't, the engine will run very unevenly
