OK.This is what happened.I removed the leaking EHA (engine would start with it) and then replaced it with another one and copied exactly the adjustment screw number of turns.Then I did not try to start it until next morning and forgot to connect the wiring to the EHA,and no start. Then I connected it and again no firing.
I pulled one plug and it is black and wet.Could that be the problem? Should I buy new plugs or clean those ?
