take out the plugs, roll over the motor and set the valves on each cylinder at TDC on the compression stroke, ( put finger over plug hole and feel for compression) ....remember what we learned in shop class for a 4 cylce engine
1. INTAKE STROKE (intake valve opens as piston goes down)
2. COMPRESSION STROKE ( both valves are closed and piston moves up to compress air gas mixture)..set the valves at TDC on this stroke
3. POWER STROKE ( spark ignites gases and piston is forced down)
4. EXHAUST STROKE ( after firing,the piston is forced down ,at BTC (bottom dead center) exhaust valve opens , piston moves up and pushes out burnt gases) piston is at TDC again , but we don't set the valves on this stoke because the intake valve is already starting to open and begining the 4 cylces all over again
