Yes Freddy, but it will get a lot harder to pull it anyway when you remove the decompressor. That is why you have to test it twice with the decompressor removed: once without oil, and once with. Remember a crankcase induction 2 stroke has compression twice per revolution. One is the crankcase compression the other is the cylinder compression. With the oil in the cylinder they should both be quite sharp resistance to pulling the cord. How much resistance there is without oil in there, is what we need to find out.
