There are a couple of "notches" in the top of the points plate - they should more or less line up with the notch in the cam bearing (point housing).alexis159 said:I read in some other website that the points should be roughly vertical - if they are not, the cam may be out 1 tooth on the sprocket or the points cam is out. http://home.modemss.brisnet.org.au/~jmi ... 50_04.html
