Alright, this one is pretty simple. I need help. I bought a long stroke york for a pretty penny on e-bay because It's too cold to go to the junkyard right now (I know I'm a wuss) Anyways, I got it in the mail today, made sure the clutch worked, and proceeded to turn it with the clutch engaged (by hand) and felt nothing on either of the ports. I started taking it apart in my basement and decided to try turning it with an electric drill to bump up the speed. It worked...kinda...when I stick my finger in the exhaust port it'll only pump air if I leave a little gap for it to flow by. If I block off the port with my finger I don't even really feel any pressure, almost like the air is just flowing back out of the intake. Is this normal at low speed? Should I rebuild it? Should I run it on my impact gun tomorrow to see what it does at a normal RPM? If it can't even put a noticable amount of pressure up against my finger at low RPM I kinda doubt it'll be able to charge a tank to 150 PSI at high RPM. Thanks for any help.
