You cannot run this for more than a few minutes without damage
I SO wanted to give this a 5 star rating! However... If you run this longer than 5 minutes... you start scoring piston rods and you MUST take it all apart and clean them off in order to keep it functional. I have run it many times... it's always the same... Run... Take apart because things are sticking... buff rods and pistons... start all over again... I will also say that it gets harder to run with every start. This is expensive... It should not be such a drag to keep running...
