No spark - Gordon

After so many attempts I, using advice from others, decided to check the valves again and found I did not have the exhaust push rod in place! The engine started when fixed but knocked loudly and finally died. Do not know where to go from here!

The push rod sits in a tiny indentation on the tappet, down the cylinder head valve valley. When you think you have push rod in correct place, rotate the engine to make sure intake and exhaust valve are moving. Then you have to set the valves to correct clearance. If you do not know how to set valves, take it to shop, don’t guess.

Why the loud knocking and then dying after a start-up?
