I just purchased a used 84 Evinrude 70 hp E70TLCRD not running with no spark. I'm sure I can get my money out of it if I don't fix the ignition problem by parting out the lower unit and power trim alone. BUT, I'm thinking about maby keeping it.
Here's the question. The engine sat in a shed for many years. I did a cold, dry cylinder compression test finding the following compression readings on the three cylinders: 114 top, 150 middle, 152 bottom.
Should I be concerned about the variance being greater than the recommended 10 to 15 psi difference between cylinders?
Could the variance between the top and the other two cylinders be caused by the engine having been stored so long?
As I recall compression readings in the 150 psi range are out of the ordinary for these 3 cylinder 70 hp models.
Help!
