Did you only check one cylinder? If you only checked one, you may have just by chance picked a cylinder that was misfiring. The most likely reason to have unburned fuel is if that cylinder isn't burning. Check ignition and compression that cylinder. But I would check the other cylinders first. A misfire may also explain your engine's poor performance.

I checked the compress in the cylinders 125-130 psi is that good?
