What is the engine model number? If you remove one spark plug at a time, it will keep running? Showing both cylinders are firing? Left cylinder dead will not keep engine running? Valve lash has been checked?
Expert:  Curtis B. replied 1 year ago.
can you remove the kill wire from the left cylinder and see if cylinder will fire?
Expert:  Curtis B. replied 1 year ago.
Only thing left would be to check the exhaust for being plugged on left side.
