Fuel problems

Really weird and frustrating issue with my 1010. I can't get gas to come out of the tank, unless I disconnect my fuel line from the carb. It's almost like there's air preventing fuel from flowing down into the carb. I've got a fuel sediment bowl (new from tractor supply) connected to the fuel tank with a rubber line running out from that. Rubber line connects to the original metal fuel line that runs to the carb. I have removed and cleaned out the lower carb section, and if I open the fuel line with the lower section of the carb removed gas flows freely through the upper section like it should. Up until yesterday afternoon I couldn't get any gas to come out the carb drain plug if the carb was assembled. I barely got the tractor to run yesterday but it really didn't want to and I'm not sure what I did to get it running. Any thoughts as to what's going on?
 
Sounds like the filter screen in the fuel inlet elbow on the carb is plugged. That elbow had a fine screen on it. They will plug up with goo from stale gas and rust from the tank.

My carb does not have an elbow filter. Also removed and blew out the elbow to make sure there was nothing blocking it. I took the carb apart and with the float removed blew air in and it was fine. If I have the lower bowl off the carb I can hook the upper carb to the gas line, open the line, and gas flows through. The problem starts as soon as I bolt that lower carb bowl on.
 
This tells me that the internal vent is shut off somehow, most likely by wrong assembly? Don't know that carb so no idea where it's at but the bowl area needs to vent to the carg throat ahead of the choke plate preferably. Should be a little hole that does this and it's been rammed full of crud? Sweat bee has built a nest in it is how some single cylinder Honda wind up in this same boat around here.
 

The carb bowl had rust in it when I took it apart. I soaked the lower half in a rust remover solution that cleaned it out real well. Any tips on cleaning that out?
 
Mine was doing this when I got it. I had a few hemlock needles in the gas tank that got wedged into the fuel tank outlet. Fuel just barely ran out the tank enough to run for a bit, then die the tractor would almost die, then run for a bit again. I took the fuel line off, cleaned that, elbow off the carb and replaced that with one with a screen, bowl off and cleaned. Drained all the old gas out and then used tweezers to get out the needles from the tank. I then did my best to blow the tank out while on the tractor. No issues since.

Did you ever rebuild your hydraulic pump? Mine had stopped leaking for a few weeks and now is back to leaking...
 

Depends on what you mean by rebuild. I pulled it off and replaced the seal on the input shaft, but that was it. The inside of it looked fine so I didn't mess with anything. I found out that I had a crack in the forward section of the rockshaft housing so I've been focused on sealing that up and haven't checked to see if the pump has been leaking.

Back to the fuel issue, the tank is clean. I can get plenty of fuel to run out if I disconnect the line from the carb. It only has an issue when I'm trying to get fuel to the carb. Really seems like a vacuum or air pressure blocking issue.
 
Sounds like you float is out of adjustment or the needle is sticking.
If I am wrong and you still think it is a venting issue then loosen but do not remove the bowl to allow air to escape and see if that makes any difference.
 

You'll probably have to split the pump in half to get to it. Remove the bolts that hold the pump together, separate the top and bottom halfs and you can get it out with a screwdriver pretty easy. The top half has all the gears and stuff so you can take those out of the lower half and use the screwdriver to get it out. Mine was a pain because it had rusted in there, but once it was out the new one went it really easily. I didn't replace any of the gaskets in my pump but they also looked to be in pretty good shape, and I haven't had any leak issues besides the tranny leak.
