Onan 4000 Dies when u let go of start switch
Hey all im new to the form. My question is for my brother inlaw. He has a 2007 weekend warrior FS23 with Onan 4000. My Gear box has the Onan 5500 its diff from his. So I need to know does this 4000 have a low pressure switch/sender? I dont see any place for it, or an oil filter. His will run untill u let go of the switch, then die, I was thinking low oil switch but cant find it? I pulled float bowl and carb is clean. Last time he used it he ran it our of fuel & did not use the trailer again for 3 months. He keeps it in storage out of town, so he could not run it once a month. Anyone have any ideas what this could be? I dont think it could be fuel pump or filter b/c it primes, When I had float bowl off I could lower float and hit prime and it was getting plenty of fuel. Maybe carb needs to come off and get cleaned. Hope its not the Control box.
Thanks for any advice
