I have a 1995 50 hp johnson and it has vro I am having a difficult time keeping it running. It fires up and I have to keep pushing in the key to keep it running. If I can manage to get it in gear and rev it up it runs great and tops out at about 5200 rpm. After 5 min it will restart fine and runs fine for the remainder of that trip. next time same drill. I have been told that is normal but I don't think so. I have about 130 compression on both cyls and spark is strong and good.I think it is a fuel problem so I cleaned carbs and replaced bulb on fuel line. It does pump up hard after a few mins the bulb is no longer hard but if I pump again it does for a few mins. what am I missing or is this normal.

Most two stroke motors need to warm up, the primer bulb will not stay hard while unit is running, it should stay hard for a while with unit off. Motor takes about 5 min to warm up, helps if you leave at a high idle for that period. If unit will still not run properly after 5 min warm up, then you have a fuel problem, remove and clean carburetors, verify all adjustments. -
