We're sorry, but your engine has been out of production long enough that parts specific to it are no longer available through us or O.S. Max, in Japan. You'll have to check with the hobby retailers who specialize in obtaining old parts for the engine collector market. Check the swap-shop areas here, on RCU, and check the classified ads in the back of the R/C model magazines. We hope you'll be able to locate the part you need.
