I have a friend's troy built power washer which I'm trouble shooting. I asked friend what happened. She said engine stalled after running for a while. She re-started engine and it stalled again. After that it wouldn't s start.
I checked the oil and it barely showed oil on the dipstick and oil was black which didn't make sense as owner bought the washer new and said it was used only 6 times. I pulled on the cord and felt like no compression. No spark. I pulled the plug and noticed that the valves move freely but the piston won't move. I tried pushing the piston down with a screw driver through the spark plug hole but no movement.
The engine is a 6.75 hp Briggs with no ohv. I'm thinking broken connecting rod.
I can get model and serial number if needed.
Any ideas? I don't want to pull the head to see if I'm right about the rod until I know that there's no other way to find out what's wrong.
The cord pulls freely with zero resistance at all.
Re: No compression
If engine is rotating and piston isn't moving then the connecting rod is probably broken.
