My to30 we'll run for 5 minutes and
shut off, I'm diagnosed it to the
carburetor. When I take the bolt out
of the bottom of the carburetor some
gas comes out, but not much. I remove
the fuel line and the L-shaped peace
with the filter screen in it. Can blow
through that with no problems. So I'm
thinking that's not the problem. I'm
thinking it must be inside the
carburetor. I remove the carburetor
and cleaned it with brake cleaner. I
stuck the nozzle of the brake cleaner
can 2 inches into the small hole in
the bottom of the carburetor (the real
small hole just big enough to get the
red plastic tip into )and flush that
out with brake cleaner. I am trying
not to split the carburetor as that
might be above my paygrade. Is there
anything else I can try before putting
this carburetor back on the tractor,
that does not involve splitting the
carburetor I don't want to take the
bottom of the carburetor off because
I'm not sure what I might find in
there and what might fall out that I
don't know where it goes. So any help
with any other suggestions I would
appreciate thank you
 
Don?t be afraid of splitting the carb. Get a complete overhaul kit which has a new float valve and seat. Your problem sounds like the float is not allowing enough fuel into the chamber, which is an adjustment to the float, or the float valve has its own issue, clogged gummed up or whatever and that my be the real problem. When ordering the kit make sure you see a black tipped float valve and not red. The red tipped ones swell with the ethanol in our gas.
 
Next time you fire it up, remove the gas cap. Keep running? The hole in the center of the cap is plugged and not venting.
Died again? You have three filters in that system. The last one in line is the brass elbow into the carb.
If you have ANY other filters added into the system, they can be just enough to stop the flow. My tractor doesn't like to flow close to empty.
The second filter in the system is the screen inside the fuel bowl and the last filter is inside the tank.
When you pulled the line at the card brass fitting, did you open the fuel line and check for flow?
No? oops.
Pull the float bowl and check the next filter for crud.
Still got problems?
Valve opened all the way into reserve?
Might be time to pull that valve, after you drain the tank, and replace it.
 
When I removed the brass elbow down at the carburetor I have good flow there, so I am assuming there is no problem from the elbow that screws into the carburetor back to the tank. I also removed the gas line coming out of the inline filter and I have good flow coming out the filter. Thanks for the reply I appreciate it
 
Then your problem is simple.
Get yourself a LARGE plastic handle screwdriver.
Remove plug at bottom of carb.
Turn on gas flow.
SMACK carby with screwdiver.
Harder.
Got flow now? Stuck float.
Turn off the gas flow, reinstall the carby float.
Problem fixed.
