Black Max Pressure Washer
If this is not allowed, please let me know. I don't have a mower question, but I have a small engine question. I'm working on a Black Max pressure washer with a Subaru EA175V motor. When trying to start it, it almost pulls my arm out of the socket! I thought it was the pump, so I pulled the pump, and no change! It pulls fine with the spark plug removed....piston moves freely. Once the spark plug is put back in, it almost pulls my arm off! This is what I've done so far: Checked for spark....good spark. Adjusted the valve clearance (OHV). Cleaned the spark arrestor. I'm thinking that maybe the flywheel key is sheared???? Any other thoughts? Thanks, in advance for the help!
