Rx-g?

Is the O.S RX-G a good engine, and will o'donnell make a red cooling head for it?

Here we go with please find this info out for me. Dude you cannot buy that red head yet its a team part so wait a year and maybe you can buy it. Yes OS engines are great. That engine is a pullstart and it is the OS RG-X not the RXG (X) meaning pullstart. It claims to give 1.9 bhp. I would go with the OS RZ-R.

I am not sure but I think its a European term Brake Horse Power. Its the same thing as Horse Power though.

its power at the crank I think

I just found this

The maximum horsepower of an engine is determined by achieving a braking horsepower equal to the output of the engine and basically stalling the engine. During the test, tension is increased on the brake drum to increase the braking force in 10 pound increment for small tractors and engines, and up to 100 pound increments for large tractors and steam engines. Engines with good governors will maintain a reasonably constant RPM until the maximum Horsepower has been reached and then the speed will drop sharply. The highest Force and RPM's gives the maximum HP for the engine.
