Customer Question

My 2014 time master back fired and now it won't start. It has no compression. I went to engage the blade and that's when it back fired. I trouble shooter just about everything. I do have spark.

What engine do you have? Remove spark plug and with a probe, feel for the piston, turn engine manually to see if the piston is moving. If piston is moving, remove the valve cover and see if the valves are moving. With zero compression, you have either a valve stuck open or a piston that has come loose from the connecting rod!
