Success! Check the kill switch as fleetwin above description, infinity reading when NO and 24 ohm when NC. I reconnected the kill switch with the circuit. Then check the choke plate when I pull the choke. A mistake found, the choke plate was not completely closed. The pivot bracket screw interfered with the mechanism! Since I did not tight enough. Then I readjusted the idle needle 2 turns out from. It ran with a couple pulls. Now I will put the lower unit together and test it on the water!
Thank everyone for the great help!
Note: just pick up 1966 20 hp Johnson for the next project! This one should be easy to work on since it has the same block but just coil and point. No low tension system as this one.
Here is the link on YouTube. Is it normal shaking when running at low RPM?
