ya...another dumb question- sorry- Reading up and getting ready to do a compression test- it says to open the carb. I understand to have the choke open but....I have a '77 400, edelbrock 600 carb....do I find a way to lock it open?
I will take the plugs out- disconnct coil- have daughter trun it the 4-5 times per cylinder. Will gas be going down through the intake and wet a cylinder throwing the reading off?
