whdave 1 #1 Posted August 13, 2010 Hey Everyone, I have a 1989 Wheel Horse 520H. I recently installed a new connecting rod and piston in the cylinder that was blown up, I didn't have any block or crank damage, the crank was not out of round or bent. What I need to know is , is it normal during acceleration to hear a little noise in the block until the motor reaches full RPM, It sounds good, but I don't really know what these things are supposed to sound like. The only ones I've had were kohlers. I know it has plenty of power and runs nice, but I am concerned about the mild chatter I hear. Thanks Dave Share this post Link to post Share on other sites
