The whole thing was given to me by someone who was not comfortable flying it. The manual says "The FS-52S engine is not fitted with a manual choke control, since it has been designed for use with an electric starter only."

What I usually do is hold my finger over the muffler exhaust and turn the engine over a few seconds with the starter - without the glow plug igniter on of course. Then I try starting it. Is this the acceptable way of priming?

Thanks again for your responses.
