Thanks for your responses to Sirio parts. So far, I have not had any luck finding the part I need in the USA. I have gone to kyosho's site and even called them, the part is not obsolete, but they do not have any in stock. They have to order them from Italy and I was told this could take a very long time.

Does anyone have an old S23 engine that is blown or doesn't run that I could take the backplate shaft from. The 23 and 27 use the same shaft, or at least has the same part number for the shaft.

This is a shame, I have a very good 27 that I have not been able to start and run.

I am hoping someone can help!

Thanks...
