Hey Guys: I have Mercury Pro Series outboard 40hp 2 stroke ( 4cyl ) 2 carb. 1996 model.
Mother in excellent condition: Problem..no gas to carbs.
. Replace fuel line & primer bulb. All fuel lines around motor. NEW fuel pump.
Still getting no gas to engine. Use Starting fluid , cranks up fine , till fluid is gone.
took carbs (2) apart / cleaned. used new gas can. (not using old tank)
Help !!! any comments ?
 
Pump installed per directions ...gas line in / gas line out ...bolted correctly to engine block ( with gasket on back ) .
remove outlet tube (to carbs) pump primer , gas comes thru. Old one worked fine last year till end of season . Was running full throttle and engine slowed down till it quit. This year i took pump out to install new diaphragm / gaskets...discovered its cheaper to buy new Pump . Could the " reed valve (on engine) not be functioning properly when piston travels up/down ? it isn't "stuck"... engine still has great compression and good fire.
