Wow! Hiking 3/8 mile to reach your house. What a different world than my coastal Southern Cali home. I searched the 1992-1995 Civic FSM, which includes your engine. Your compression ratio was slightly higher than other Civics of that generation at 9.3 (instead of 9.2 or 9.1 for other trims). But a document search turned up no results for compression test. I might search again. But I think 184 is the more precise number and you are more than 10% over that. High compression can be associated with pre ignition.

EDIT: I found a compression reference in the service limits section. 184 +/- 28 is considered within limits. See attached screen shot.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
