92 honda civic vx. 102k miles. 1.5L vtec

I just ran the compression test. For the dry test the results were: cylinder1: 195psi (6 cranks) 2: 200psi (7 cranks) 3: 200psi (8 cranks) 4: 200psi (8 cranks)
wet test results: cylinder 1: 220psi (7 cranks) 2: 230psi (8 cranks) 3: 230psi (8 cranks) 4: 230psi (7 cranks).

I was told that it should be reading 125-135psi on the dry test. Why do you think it is consistently reading so much higher?

Do you
have the same problem?

Carbon build-up in the combustion chamber will raise the compression pressure or a head resurfacing job.

Try engine decarbonizing-might work

How do I do engine decarbonizing? And if I need to buy anything what do you recommend buying?
Thanks

In today's high tech-everyday is new stuffs-check Autozone or Napa and select the best and follow instruction. Or just bring it in and have them do it -they got the machine.
