Did a compression test on a non-running David Bradley I set aside to restore and it showed around 80 psi. Thought this was low, did compression tests on 3 other old junker DB's lying around and they were all about the same, between 70-85 psi. Dropped a bit of gas mix in the cylinder of the saw in question, gave it a crank and it fired and seemed to have the sound of a saw that might have some life left in it. QUESTION: Did older saws like this have a lower compression standard? Is this normal? Thanks
