Does anyone know anything about the anti-siphon valve at the top of the Roosa Master fuel pump on the 310 Waukesha?
I have turbocharged 310 Waukesha that I was out mowing with all day. At the end of the day, it began to bog down and eventually died. The next day, I got it running and took it to the fuel barrel.
I topped it off with 18 gallons, so it was about half full. I replaced the glass fuel filter which looked perfectly clean. The fuel ran freely out of the tractor tank. The air filter is pristine. I went back out to mow and at first it ran fine but within 1/2 to 3/4 of a mile it died again. It would not start right away. An hour later, I drove the tractor back to the house.
There is no unusual smoke. The engine runs smoothly and sounds fine. It pulls with full authority until it starts to bog down, then it acts like is is under load and eventually dies.
I"m wondering if the anti-siphon valve on the top of the pump is bad and lets the pump build up pressure so it essentially runs itself out of fuel?
