Hi Deejay,
I do thank you for your comments. But my reference to the machine cutting unevenly was on my fathers new Scott Bonnar back in 1977. Not my old Scott Bonnar motor that I am rebuilding at the moment. Maybe my father Scott Bonnar had a chassis alignment problem from new? I don't know, But there are many more people out there reporting this same problem. To a trained eye, this uneven cut finish can be seen. Not a big problem to most, but to say the finish cut is even, this is not the true. This is why I have asking this forum regarding the motor position, to find out the design reason behind the engine being offset, as well as doing my own investigation to find out if it is a chassis misaligned problem as you put it in your own words is the problem.
