Thanks for letting me in here! I have been sorting thru archive threads but decided to start over. My motor started running out of fuel pressure. It would run fine, and then stall. After pumping the too soft bulb it might run fine for days or weeks but problem has progressivly got worse lately to the point it's a bulb pumping every half mile. Checked everything from pick up in tank to engine, changed fuel lines, took apart tank swapping valve, anti siphon valves, checked primer bulb for proper check valve operation and if anything was in it possibly obstructing flow. Acts like vent problem so ran it without gas cap. I hooked up a fuel pressure gauge in carb line and had fluctuating pressure from 2/12 to 1lb. Book says at least 3lb. So looks like VRO. I checked pulse limiter, looked to be ok. Carb cleanered it anyway. This is 2nd go around with this deal so I have the pump that was taken off a few years ago. Me and my Dad who was a career auto mechanic and really sharp dude took it apart and could find nothing wrong with it except poppet screw a little bit looser than spec. Anyone know what causes the pump to fail? Not a moneybags and hate to spend $450 again if I don't have to. Thinking about putting tightened up old pump back on and see what happens. Damn OMC for shutting down the rebuild kits..... Thanks for any info
