- Turn the crankshaft until the TDC mark on the dampener ring is lined up with the pointer on the front cover. As you turn the crankshaft there are 2 marks on the edge of the pulley. The first one that comes up is the timing mark, so use the one to the left. This will put the engine on TDC on #4 or TDC on #1 (it doesn’t matter). If your valves are all out of adjustment and you cannot determine which cylinder is on compression, turn the crankshaft until the #1 cylinder valves are both completely closed.
- Adjust cylinder #1 intake valve and the exhaust valve.
- Adjust cylinder #2 intake only.
- Adjust cylinder #3 and adjust the exhaust valve.
- Now rotate the crank one full turn and bring it back up to TDC on the lower mark. Adjust cylinder #4 intake and exhaust.
- Adjust cylinder #3 intake valve.
- Adjust cylinder #2 exhaust valve and you are done.
