OS Max 40 RC
Mike,
We're sorry, but your engine is so old that neither we nor O.S. would have parts for your engine, and we'd not know who might have any.
You'll have to check with the sellers of engines and parts for the collector's market. They usuallly advertise in the back of the model magazines.
You can also advertise in the 'swap shop' area here on RCU. If anyone can help you, you'll get answers.
