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
ENGLISH
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 people, things or animals around.
Furthermore check that all the nuts are well tightened and check the
fuel system.

3.1- DELL'ORTO CARBURETOR

Fill up the fuel system; petrol must reach the petrol entry hole and later
pump for three times (using the Polini manual pump - item 316.0016)
to fill up the bowl. To start the engine pull upwards the starter level
(photo 1) placed in the upper side of the carburator. Operate the starter
without accelerating till the engine starts. Once it starts, switch the engi-
ne off or disconnect the starter by lowering it or by starting the engine
again and gently accelerating, if necessary.
!
ATTENTION: keep the switch off button in your hand during all
the stages and be ready to work it in case of any anomaly. If necessary
keep it pressed till the engine has completely stopped.
After starting the engine we suggest testing the right functioning of
the kill switch button. After having checked it, start the engine again
without accelerating and without using the starter. Now start the engine
and let it idle until it warms up to normal temperature
4- RUNNING IN

transmission bed in correctly and to ensure continuous reliability in fu-
ture. Respect the following instructions: once the engine starts, leave it
idling until it warms up to normal temperature. We suggest running the
