I have a 2000 90 horse johnson with excessive oil consumption and at WOT it will bogg down. I have been looking for a vacuum leak and cannot find one with a vacuum pump. I dont have an antisiphon valve or any other type of restrictions of fuel. It has a new OEM VRO pump on it. At WOT it will bogg down unless you hold in on the key. The secondary fuel pump has a weep hole in it and if you unplug the hose from the block it will not hold vacuum.Any suggestions would be appreciated.
