Compression test numbers seem high? 1800

I am just guessing that maybe the compression ratio is higher than you calculated. I did an engine a few years back that was about 10:1 & compression test was yielding about 185-190. I had the same issue with dieselling. With the crappy gas we get these days I ended up breaking all 4 top rings due to detonation. I guess the only real solutions are: retard timing, use avgas, or use water injection
