There are 2 different "Moki" engine companies with the same name produced in the same country (Hungary). One produces glow engines distributed in the US by Horizon (1.35, 1.8, and 2.10"). The other produces gasoline motors sold in the US under the badge of RCS (RCShowcase). They are sold in the UK as Mackay and in Germany as Moki - isn't that confusing. The Moki gas engines are not conversions of the Moki glow motor - totally distinct designs from the ground up. I don't know of any conversions of the Moki glow motors. I doubt it would be worth the cost to convert considering there are plenty of gas ignition motors on the market that cost only a little more than the Moki glow motors.
