Hard copies of MB manuals are getting hard to come by and collectively, are expensive. For example, a reprint of a 103 Engine Manual is about $100.00.
For a few $$$ more, you can get a CD-Rom that has alot more on it than just the engine manual. I happen to have both. In my opinion, the CD-Rom is a DIYERs best choice.

M103 - SOHC
James Madison - Oppressors can tyrannize only when they achieve a standing army, an enslaved press, and a disarmed populace.
Liberty Firearms Training - After years of trying to regulate California criminals with a never ending stream of gun control laws they have still not given up with the belief that if they make something a crime that criminals will miraculously start obeying the law.
