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?
( deeply explain all point of question)
While discussing quick-disconnect fuel line fittings: Technician A says that on some hand-releasable, quick-disconnect fittings, the fitting may be removed by pulling on the fuel line. Technician B says that some hand-releasable, quick-disconnect fittings may be disconnected by twisting the large connector collar in both directions and pulling on the connector. Who is correct?
