So I bought a 1984 johnson 8hp motor a few months back that was running. After taking it out a few times it was very hard to start. Changed the spark plugs and that helped. Then again I was having trouble starting it so I did multiple tests and changed out the power pack. Then it started running again. Took it out the other day and it was running but not up to full speed. After running it for awhile it would jump up to full speed then bog back down. I thought maybe it wasn't getting enough fuel so I bought a new primer bulb and replaced that. Went to take it out the ther day and it started up then kicked right off. Haven't been able to start it since . I've also put in a new water impeller kit, carberator kit and new coil ignition. Any advice would be great
