I'm guessing you can't exactly bolt a full crank or Powertorque onto a twin base.
No it would not bolt up to a Twin base.They are made only for the Twin cylinder engines.As seen below,bottom picture is a Compact base.
Although if you wanted to put a Lightweight or Compact engine on it (Not sure why anyone would) It would fit.Would look very very strange but would fit.
