[QUOTE="CMOS, post: 432714, member: 15462"] Update 4-15-17: I did a test by placing the fuel tank above the motor itself (on top of my pickup toolbox), and the water supply was a barrel (no muffs). As before I was able to get her started at normal idle. I just left it in the driveway and sat down and watched. After about 4 minutes it died. Started it right backup, but at low idle again. Gave it some throttle and after a few seconds I could hear the RPM jump. Back off throttle, back to normal idle. After less than a minute, back to low idle and died. I was able to repeat this same thing for over 30 minutes. It will idle fine for short period of time, then low, rough idle. I did find a small air leak in the hose fitting going into the fuel pump. Tightened it up. Still the same symptoms. I also checked the fuel pump metal screen filter. Super clean. When it does idle at normal RPM's it's as smooth as glass, but it doesn't last long. Question: when operating with the muffs, where should I see water OUTPUT other than the pee hole? I'm not seeing any water exit the engine other than the pee hole. Related? Thoughts? CMOS [/QUOTE]
