You can use the M2C clutch and flywheel on the Go engines, I have used them for over a year, you will need to shim between the front bearing and the collet, or cone washer if you will, just make sure you get the right size, I think it's 7 or 8 mm ID, and you want it to ride on the inner bearing race and the base of the collet, check the thickness, usually it will take about a 3mm shim, just enough so it does not rub.
