No offence intended here but--> anyone writing a book about minis 30 years ago may not have experienced such worn or stuffed-with components as we are finding these days.

You should put your heart & soul into everything you do.

And for those playing at home, out of the three basic types of carb, side, up and down draft, the su is of the side draft variety. Same as dellortos and webers.
