Gas problems

[dick r]

i have a 2182 that acts like it is starveing for gas after about 1 hour of mowing at 3/4 throttle. if i pull choke out a little it will recover and run fine. put choke in problem repeats.i have replaced all gas lines,fuel filter, cleaned carb,fuel inlet in carb, gas shut off valves. when i remove gas line at carb. and turn switch on it pumps a full stream

Sounds like a plugged vent for the fuel tank. You should be mowing at full throttle. Mowing at 3/4 throttle means the engine isn't spinning fast enough for the air coming off the flywheel to cool the engine properly this extra heat could also be contributing to the issue.

always mow at full throttle

After further investigation it would appear your tractor has a liquid cooled engine so heat probably isn't an issue. Next time you mow wait for it to start cutting out and loosen the gas cap, that will confirm a vent issue. If it doesn't change anything then your issue is elsewhere.

I was going to say that the 2182 has a liquid cooled Kubota WG600..... but I guess Tim figured it out.

I want to add, the reason you need to run a mower at full throttle has NOTHING to do with cooling.... but the efficiency of the deck. The vacuum on the deck is greatly reduced at lower speeds. The flywheel on an air cooled engine will sufficiently cool the engine at whatever speed it is running. I'm quite certain of that.

As far as your issue goes, you could have a few issues.
1.) There is still something blocking the main jet in the carb. I don't care if you've cleaned it before, it may have something in it. I've seen a small piece of rubber from a new fuel line plug a main jet. Personally, I always blow or flush fuel lines prior to install. But, even then, a small piece can come off during installation on the hose barb.

2.) You did not say you removed and flushed the tank, or removed and either cleaned or changed the fuel shut off fittings in the tank. These fittings are known to plug off, and the shape of the tank makes it difficult to thoroughly clean.

I suguest you pull the tank, and remove the shut off valves and clean or replace them (you'll need new grommets). I'd probably go ahead and take the carb apart again and check it out good. A new filter wouldn't be a bad idea. I'm betting the tank valves are plugged, or something is floating in the tank. Very common issue. Plugged fuel vents are almost unheard of. They have a pretty big vent, and honestly not a very well sealed one. They almost never plug.

first i would like to thank tim and johathan for the reply . i did not state very clear i guess that i have removed and cleaned the gas tank washed it out and blew it out with air from all holes, tank gas valves were removed and cleaned with compressed air also,new tank rubbers installed. also if i mow at full or 3/4th throttle has little to do with my gas problem, it just effects how it cuts the grass.is there a way to check the fuel pump for volume? problems always seam to start when engine is hot

[J-Mech]

Unhook the hose and see how much it pumps. If you want to get real technical, run the pump a min and measure the amount it puts out. (Unnecessary) Visually is good enough. I'd suggest checking it hot.

I don't recall..... is there a fuel shut off solenoid on that carb?

[dick r]

yes jonathan there is a fuel solenoid shut off on the carb.

[J-Mech]

I'd check it out and see if it is getting weak. If it is getting hot and trying to close, (going bad) or if the plunger tip is starting to come apart, that will cause this issue.

Carbs on 2182s are ridiculously lean to start with, any and I mean any, little thing will cause this lean problem.
They don’t sell kits for the carbs.
I had one carb I gave up on and got a new one. $160 or so.
But since it’s doing it hot I second Js advise on the solenoid or the pump.
Just throwing this out there: I’ve cut all my solenoid plungers off, just let your engine idle for a few minutes before you turn off the key. I’ve never had a backfire.
