2- FUEL
Thor is a 2-stroke engine that needs oil/petrol mixture. Only use good
lead-free petrol (ES) purchased by a petrol station with at least 95 octa-
nes. Add good 2,5% synthetic oil of good quality to the petrol.
Never keep the petrol into containers for a long time because its quality
will be damaged. Only use certified metallic containers for petrol carria-
ge. Mix up the petrol with the oil ONLY when you are using it.
!
WARNING:
The nature of the carbon deposits on the cylinder
head, spark plug and exhaust port give important information about
the fuel mixture burning in your engine. Remember that mixes that
contain too much oil do not extend the engine’s life.
!
CAUTION!
Petrol is extremely inflammable and explosive. Car-
ry out these operations in a well ventilate place and with the engine
switched off. Refrain from smoking and avoid all naked flames or sparks
where petrol is being drained or where re-fuelling is being performed.
!
CAUTION!
For American customers only. The European range of
octane is different from the American one:
e.g. EU (E5) 95 OCTANE = US 91 OCTANE / EU 98 OCTANE = US 93
OCTANE
For THOR engines you have to use a high-octane gasoline (not less than
US 91) maximum 5% of Ethanol.
!
ATTENTION!
It is important to use 100 LL AVGAS in case the fuel
above mentioned is not available.
3- ENGINE STARTING
Start the engine only when all is in good conditions and perfectly wor-
king and check that there aren’t persons, things or animals around.
Furthermore check that all the nuts are well tightened.
3.1- MANUAL STARTER
Fill in the fuel system till the petrol reaches the carburetor hole and
then pump up three times (using the Polini manual bulb- Code
316.0016) to fill in the bowl. To start the engine pull upwards the black
level placed in the upper side of the carburettor. Operate the starter
without accelerating till the engine starts. Once it runs switch it off, di-
sconnect the starter and start the engine again slightly accelerating. For
your safety only start the engine after your harness has been COMPLE-
TELY fixed!
3.2- ELECTRIC STARTER
Fill the fuel system in as shown in the previous paragraph.
If your engine is equipped with a Polini throttle control press the two
black buttons together and slightly accelerate till the engine runs. If
necessary operate the starter to make the engine starter easier when it
is cold. If the engine is not equipped with a Polini throttle control plea-
se refer to the instructions of the vehicle’s manufacturer to find out the
switch on/off buttons.
!
ATTENTION:
keep the switch in your hand during all the stages
and be ready to operate it in case of any technical fault. If necessary
keep it pressed till the engine has completely stopped.
Once the engine starts we suggest testing the right functioning of the
kill switch button. After having checked it, start the engine again wi-
thout accelerating and without using the starter. Now start the engine
and leave it idling until it warms up to normal operating temperature.
