Question on compression test

I'm hoping that the oil got diluted from the old fuel pump bc the new one on it now is still outta the box shiny and pumps fuel just fine. I will check on the thermostat tho. The engine does run just barely wants to get out of its own way it seems. I'm gonna go do the compression test now I'll post what I find out. I'm hoping the readings are all close bc I would rather not have to tear this thing down. As for the testing the engine has to be warm and the coil disconnected from the battery correct?
