Note: 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.
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 may have a different propeller bolt pattern than the Thor 130 EVO, depending on the model year.
Flash starter – The Polini Thor manual starter has some serious problems. 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.

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.
