I need to know how much compression my cylinder should have. I checked it and it shows 60 psi, I think that is low. Does anyone know what the compression number should be is on my gcv190?

I believe that is correct.

Does the GCV190 engine have a decompression feature on the exhaust valve as the older GXV 120 - 140 engines? If so, that would need to be deactivated to get a proper reading for compression.

What? Take apart the engine just to get a better reading? Heard them all now.

No, you do not take apart the engine. On the GXV engines you simply remove the valve cover and slide the rocker arm off of the exhaust valve, pull out the push rod and then pull the rope. Look it up, google is your friend.

Which is not taking apart the engine? Removing the valve cover? Sliding the rocker arm off? Pulling OUT a push rod? I'm dumb YES, but sounds like taking "something" apart to me.

Well, if that is too much for you to get a proper reading so be it. I don't understand why you would have such a tone when all I was asking was a simple question about the GCV engines. Go about your day and perhaps someone else will answer my question about the GCV engine as I was asking.

61 psi according to the Honda shop manual. Some versions have a compression of 71 psi And those are measured at cranking speed with the compression release activated.
