I have a 1974 Johnson 9.9 hp. I cranked it yesterday it ran for a few minutes then it quite. I could not get it started again. I pulled the gas line off the carb that comes from full pump. I pumped the primer bulb and it squirted gas out of this gas line. I pulled the pull rope and a little gas came out of the gas line. I checked the screen in the fuel pump, it was ok. I connected the gas lines back and wiped up the spilled gas. I pulled spark plugs out one at time connected plug wire to it and held plug end (with insulated pliers) to the block and had wife pull the pull rope. It was dark by this time so I could see the blue spark, had spark on both plugs. The gas hoses look ok. My primer bulb gets hard when I pump it and it stays hard the whole time. I have had this boat a couple of months and it has never really run perfectly. It has acted like it was not getting enough fuel, the motor would bog when giving it full throttle. I had replaced gas hose/primer bulb from tank to motor. Yesterday I put on a new plastic gas tank, the old tank had a split in it and I thought that might be my problem. I had my wife keeps pumping primer bulb while I tried to start motor and no luck. I tried again today and no luck. I cleaned the spark plugs with gas before I cranked it the first time. I checked them when I pulled them out to check spark. Can anybody gives me any ideas what to check or try?
