Re: Owners Manual Needed
I disagree in a sense about the service manual vs. the owner's manual.
I try to find a simple owner's manual for every old engine I get. This manual tells you the normal, simple owner-maintenance things that an owner needs to do. Especially one who has no inclination or ability to do repairs.
The service manual often (usually or always in my experience) doesn't have clear and simple normal owner maintenance instructions or schedules.
I actually have both for the three 1990 and earlier engines I own, and both have their purpose. If OP is simply interested in owning and doing simple maintenance, the owner's manual is the best bet.
OP: look on ebay. You may or may not find the actual manual you need, but you might find a path to someone who carries this type of thing and you might be able to find one for cheap.
