I recently purchased an almost new 60 size Twist that has a MDS 68. When I found out thart the engines/parts were no longer available I was very upset with the shop owner for not telling me. I have mostly forgiven him because the engines runs like a dream, is very strong and tunes well. It appears to be one of the last MDS engine designs with a great carb and alot of power. Very reliable. Guess I have to hope it is also long lived.

I have sent several e-mails to the mfg. without qany reply.
