This is quite possibly, one of the best two stroke nitro engines that o.s. ever made. Very resilient to
Idle mixture adjustment. Can be adjusted a little wrong and still run well.Very durable to many types
of environment's and a all out joy to own. If you are lucky enough to buy a new one. It will last you for a long time, with correct fuel and general care. Always follow owners manual instructions which are readily available online.
