Hi all,
My 2013 Workmaster 35 is having running issues. It will start and idle, but if I throttle up, it struggles. I've checked the fuel line to the tank for problems (none), and replaced the fuel filter, but it still has problems. However, when I tried to bleed the fuel filter via the manual pump on the top of the filter housing, nothing comes out of the bleed screw, no matter how many times I push the pump. I can hear air being pushed out of the bleed screw. Some fuel must be getting through since the engine does run. If I let the tractor sit for 15 mins "off", and then start it, I can rev it up to full throttle (2700-2800 rpms), but after 30 secs it dies down to about 1000 rpm and stumbles around that range. It definitely seems like a lack of fuel.
Question: is the manual pump knob on the filter housing supposed to "close" (pushed down position) while running? I noticed it slowly closes (~ 1 min) after starting the tractor.....just about the time that the problems start. However, after sitting for a while not running, the knob slowly eases back to the up position. Maybe this is how it is supposed to work, but I can't find anything about it in the service manual. I'm curious if the filter housing pump has a problem or clog, slowing the fuel down.
