I have a model J5RHLCNR and when I look at the parts list some of the items have 4.5 after them and some have 7.5, for example, "Magneto - 4.5" and "Magneto - 7.5"; why is this?
those motors share a whole bunch of parts......so much so, you could use a 4.5 as a parts motor for a 7.5, or vice versa. ( obviously excluding the parts listed as being unique to either)
