How do I disable the fuel pump to do a compression test?
I know some of my valve seats are trash because I can see exhaust coming from my valve covers. When I do a compression test to see which ones need recut fuel sprays out of the unplugged cylinders. :\
Thanks in advance.

Exhaust from the breather is not a valve issue. That is worn compression rings, blowing air down into the block and out any open hole.
If you have gas blowing out a cylinder, then you have carb issues. I've never had to disable the pump to do a compression test. Leaving the carb alone, it should not draw that much fuel to get wet.
