Default How's my compression?

Stock b16a with 93k miles:

cylinder 1: 181
cylinder 2: 185
cylinder 3: 195
cylinder 4: 195

*Don't know why cylinder 1 is so much lower than 3 and 4.

thats not too bad. did you check it again after adding a few drops of motor oil to each cylinder? if its considerably higher, then it shows worn rings as the oil will help seal them.

What would be considered normal compression for a stock b16a? I'll probably test again soon. Is there anything I didnt do right? Here's what I did:
engine was warm, pulled the 15a fuse for f/i and the 15a fuse for the ecu, removed all plugs, cranked engine 6-7 times.
If I can get better compression on the next test, I will probably keep my civic otherwise I may sell it and get either a gsr, prelude or rsx-type s.
