d. High resistance in both the primary and secondary circuit
What does a slope in the spark line represent?
An engine starts and runs briefly after a small quantity of fuel is put into the spark plug hole, but it doesn't not start when fuel is added to the carburetor throat. Tech a says that the problem may be that the exhaust valve is not closing completely due to carbon buildup. Tech b says it may be due to a defective carburetor mounting gasket. Who is correct?
