Hi~
Sorry I got you misunderstanding.
The OS GT-33 is not the glow engine with fuel of Methanol.
it's typical Gasoline Engine used the fuel of Petrol. but the ignition system can be replaced with glow plug.
The Gasoline is ignited by glow plug not the spark ignition plug. this new glow plug for Gasoline GT33 has been launched from OCt. 2015.
