The engine will crank but will not start. Carb chk out OK. Spark plug is firing. Pulled valve cover off ohv and they appear to be working OK, moving in & out and seems normal to me.
I removed spark plug and placed a pencil in hole up to piston. Piston does not seem to be moving due to no compression. I am struck. Do I need to go into engine to see if the rod conector is broke or ck piston etc. what should I do next in trouble shooting my problem?
