Polini Thor 130

Note: the WG is out of general production and all production may end soon.  It is still available from some paramotor shops but is more than double the cost a year ago.  The WB may be used in place of the WG and is still available on the open market.  The WB carburetors do not have a choke, however.

The Thor models share a common design.  The info below is unique for the 130 (not the Thor 130 EVO).  Please see the Thor models section for info that is not found here.  The Top 80 section has detailed info on things like the Walbro carburetor function and tune up which is used by Miniplane and Polini engines).  There are also various troubleshooting issues that are addressed.

Carburetor – Walbro WG information, adjustment, & repair  Main jet is a #130.

Choke – What does it do?  Why have it?

Cylinder head, temperature, maximum – 230°C and 250°C maximum running temperature, never exceed 265°C/280°C but only for a few seconds.

Dimensions – this model has a different propeller bolt pattern than the Thor 130 EVO

Flash starter – The Polini Thor manual starter is an engineering disaster.  Here is a permanent fix.

Fuel consumption, performance tuned – 1.6L/hr. (0.42 gal/hr.) Range is approx. 7.5 hours for 12 liters of fuel.  Inexpensive and reflex gliders, wooden propellers, heavy pilots, and un-tuned engines will burn considerably more.

Parts diagram Thor 130 – Note Polini updates these lists frequently so this diagram may not be 100% accurate.

Propeller bolt patterns – newer models have (6) 6mm bolts spaced at 50mm across, older models have (4) bolts spaced at 60mm across

Spark plug NGK BR10EG gap 0.9mm (0.035")  This is a resistor-type plug.  Pilots may also use the B10EG/ES or the B9EG/ES.  Use of a non-resistor plug may increase the amount of noise created by the ignition that is picked up by a two-way radio.
