G'day

For what it is worth here is my brief experience with MDS engines.

A friend in our club was given two by his brother. They had not been used for about 15 years. One was a 46, the other a 60.

We put the 46 in a Kadet Senior. It fired up easily and was the best smoothest idling two stroke I have ever met. But, in the midrange it was hopelessly rich and spluttered and coughed when more power was asked for. Once it cleared, its top end was fine. In desperation I put the carby from a Super Tigre 40 on it. It was perfect so we left it like this.

The 60 was in a 96 inch Telemaster Senior. I was worried that it would be like the 46 but it just ran perfectly. Nice idle, like its smaller brother, smooth transition and mid range and good top end. It was perhaps not as powerful as modern 60s but ran well and pulled the Telemaster into the air on half throttle.

Neither was converted to diesel.

So one ran well, the other needed a different carby. That is about the same score I have had with Chinese two strokes.
