Hello, The two engines pictured look much the same.
I haven't had these engines before and plan to make one out of these two.
The donor engine (off a Scott Bonner) has carb missing & more.
It will give up its starter and starter cup & magneto.
I think I have read in some threads here that parts are inter changeable.
