Once again thank you for the welcomes.

 Roger B I don't think they would be powerful enough to function as a starter motor unless it has been geared down. The one I am experimenting with puts out 35 watts. The AC output was connected directly to three light globes using a delta connection.

I posted a link in the engines section of a engine I made driving a brushless DC motor as a alternator.

Bill,

My thoughts were on a slightly different size range. The brushless motors used in the model cars and aeroplanes have quite high short term outputs, some hundreds of watts. They also are designed for high speeds, 10,000 rpm plus. I would have to do a few calculations, but one of these geared up 3 or 4 - 1 coupled to a 15 - 20cc engine would probably work as starter and generator.
Best regards

Roger

I had not thought of model aircraft and cars and if you have a high rpm engine those brushless DC motors will work well as a generator and starter motor
