i read recently in the forum that you could put an mc16 motor into a mc18 frame.
not realy me thinks the front mounting holes on the cases are the same it's when you get to the rear that the problem starts the top mounting lug on the 16 engine is diferent also there is a mounting lug missing on the lower left side of the 16 motor.
The 18 engine is rubber mounted where the 16 on the rear is not.
Has anyone managed to swap these motors sucesfuly?
Andy,why can't you change the cranks from the 16 into the 18?
